== RouterBoard 532A ==
2014-Mar-18 Currently has [http://x-wrt.org X-Wrt] software installed on it.


In DNS, it's called OpenWRT and can be reached via ssh or https://openwrt
== Overview ==
or from outside the lan at https://alseageo.dyndns.biz/


Support for it in [[OpenWrt]] seems to be pretty good, they have the latest releases prebuilt for it. I used instructions in this page to get it loaded.
This page is about RB532A. is a surplus piece of hardware that worked for a time as a firewall at work, then as an openvpn server at my house.

== To-do ==
 
* QoS
* dmz - allow OpenVpn access ?
* OpenVPN - switch over from Kilchis?
* Scheduled QoS control?
* Crow? or similar
* WoL
 
I tried to override the WAN interface default MAC address so that Comcast would not change our public IP address but for some reason that feature in the GUI fails.
 
=== Reflashing ===

The simplest way is to simply download the CF image file from http://downloads.x-wrt.org/xwrt/kamikaze/ and then use 'dd' to copy it to a CF card, then put the CF into the RouterBoard and off you go.
 
Get the 128k image. The '''128k''' refers to the block size in the filesystem and it's good for CF cards.
 
The healthy way to copy binary images to CF is 'dd' under Linux.
Cygwin includes a 'dd' command so if you are burdened with Windows you can still use dd. I did not get it working and ended up simply usng Linux. YMMV http://www.groupsrv.com/linux/about17777.html
 
dd if=/dev/sdb of=backupimage.bin
dd if=openwrt-rb532-jffs2-128k.bin of=/dev/sdb
 
The backup image is 256MB because that's the device size. Wastes some disk space but then again I delete it as soon as the RouterBoard is up and running again.
 
== Available distributions ==
 
OpenWRT and X-WRT are installed.

MAC numbers
== Miscellaneous configuration notes ==


* eth0 00:0c:42:10:1c:6c
=== Password ===
* eth1 00:0c:42:10:1c:6d
* eth2 00:0c:42:10:1c:6e


=== Miscellaneous onfiguration ===
Root password set from the console port command line using "passwd".
Set to the usual root password.


==== Password ====
=== Network ===


Root password set from the console port command line using "passwd".
I hand edited this config file to create three networks. Should be possible to do it all from the GUI but maybe that did not work back when I originally set it up.
Set to the usual root password.
 
The WAN interface has its MAC address overridden so that it uses the same MAC as the old D-Link router. That way switching back and forth between the RouterBoard and the D-Link should not cause our Comcast DHCP address to change.
 
Note this did not work -- maybe I have the syntax wrong in the file? I had to go into the command line and override the setting like this
 
ifconfig eth0 down
ifconfig eth0 hw ether '00:0D:88:5F:E8:90'
 
It loses the settings when I reboot, so I am ignoring it for the moment. We have a new IP address, darn.

=== Route command ===
 
Adding a default route so that you can get the webif stuff running initially; you need to add some packages.
 
route add default gw 192.168.123.254
 
=== Packages added ===
 
After getting webif running I use it to make these package additions/deletions.

ntpd
openvpn
tcpdump
wol
nbd's QoS scripts
 
Packages removed

We provide DHCP only to the DMZ zone.

=== DNS ===
 
dnsmasq is installed but I am not currently using it.
 
I put this in /etc/resolv.conf so that it will use Kilchis to resolve names.
 
nameserver 10.127.32.27
domain alseageo.com
 
=== Dyndns ===
 
There is a DynDNS tab under Network in the GUI. You can install and configure dyndns service.
 
Another way to do this is via ddclient on Kilchis, which is currently disabled.
It used to run once per hour from /etc/cron.hourly/ddclient.
 
The config file for dyndns on the routerboard is /etc/config/updatedd:
 
config 'updatedd'
        option 'update' '0'
        option 'service' 'changeip'
        option 'username' 'alseageo'

=== QoS ===
 
Install but not configured yet.
I'd like to use this to control bandwidth used for offsite backups.
I want full utilization at night and 200 Kbps during business hours.
A way to switch it down to a low bandwidth manually would be good.
 
=== SNMP ===
 
Installed but not configured yet. Could be set to log to [[Cacti]] on Kilchis

= Set up =
 
Support for the RouterBoard in [[OpenWrt]] seems to be pretty good, they have the latest releases prebuilt for the RouterBoard.
 
Install took 10 minutes including opening up the case. [http://wiki.openwrt.org/OpenWrtDocs/Hardware/Mikrotik/RB532?highlight=%28OpenWrtDocs/Hardware%29 OpenWrtDocs/Hardware/Mikrotik/RB532]
 
Support in dd-wrt is not good. There is an old beta.
 
== Reflashing with OpenWrt X-Wrt ==
 
http://wiki.openwrt.org/OpenWrtDocs/Hardware/Mikrotik/RB532
 
The simplest way is to download the CF image file from http://downloads.x-wrt.org/xwrt/kamikaze/ and then use 'dd' to copy it to a CF card, then put the CF into the RouterBoard and off you go.
 
Get the 128k image. The '''128k''' refers to the block size in the filesystem and it's good for CF cards.
 
Use the 'dd' command under Linux or Macintosh to copy the image to the CF card.
Cygwin includes a 'dd' command so if you are burdened with Windows you can still use dd. I did not get it working and ended up simply usng Linux. YMMV http://www.groupsrv.com/linux/about17777.html
 
dd if=/dev/sdb of=backupimage.bin
dd if=openwrt-rb532-jffs2-128k.bin of=/dev/sdb
 
The backup image is 256MB because that's the device size. Wastes some disk space but then again I delete it as soon as the RouterBoard is up and running again.
 
On my Macintosh with a USB card reader the command is almost the same, Macs are pretty cool actually.
 
sudo dd if=openwrt-rb532-jffs2-12k.bin of=/dev/disk1
 
 
= Configuration as gateway router =
 
== To-do ==
 
* Fix routing table
* dyndns updates
* ntp server? (client is working) (ntpd is installed)
* QoS
* netmeeting - use dmz
* dmz - allow OpenVpn access ?
* WiFi -
* DHCP for LAN?
* [[OpenVPN]]
* Scheduled QoS control?
* Crow? or similar
* WoL
 
== Serial console setting ==
 
Connect a serial cable and use "screen /dev/ttyS0 115200"
 
== Password ==
 
Root password set from the console port command line using "passwd".
Set to the usual root password.
 
== Ethernet ports ==
 
There are three, the one to the left of the serial port is eth0
To the right are eth1 and eth2
 
== Network ==
 
This is the '''/etc/config/network''' file, hand edited to create two networks.
There is a third etherport port (eth1) that is currently unused.

Overview

This page is about RB532A. is a surplus piece of hardware that worked for a time as a firewall at work, then as an openvpn server at my house.

To-do

  • QoS
  • dmz - allow OpenVpn access ?
  • OpenVPN - switch over from Kilchis?
  • Scheduled QoS control?
  • Crow? or similar
  • WoL

I tried to override the WAN interface default MAC address so that Comcast would not change our public IP address but for some reason that feature in the GUI fails.

Reflashing

http://wiki.openwrt.org/OpenWrtDocs/Hardware/Mikrotik/RB532

The simplest way is to simply download the CF image file from http://downloads.x-wrt.org/xwrt/kamikaze/ and then use 'dd' to copy it to a CF card, then put the CF into the RouterBoard and off you go.

Get the 128k image. The 128k refers to the block size in the filesystem and it's good for CF cards.

The healthy way to copy binary images to CF is 'dd' under Linux. Cygwin includes a 'dd' command so if you are burdened with Windows you can still use dd. I did not get it working and ended up simply usng Linux. YMMV http://www.groupsrv.com/linux/about17777.html 

dd if=/dev/sdb of=backupimage.bin
dd if=openwrt-rb532-jffs2-128k.bin of=/dev/sdb

The backup image is 256MB because that's the device size. Wastes some disk space but then again I delete it as soon as the RouterBoard is up and running again.

Available distributions

OpenWRT and X-WRT are installed.

Support for it in OpenWrt seems to be pretty good, they have the latest releases prebuilt for the RouterBoard. I used instructions in this page to get it loaded.

I installed KAMIKAZE (7.09) then later I found out about X-WRT and installed their version from http://downloads.x-wrt.org/xwrt/kamikaze/

I no longer put all 4 screws into the MicroTik case. :-)

Install took 10 minutes including opening up the case. OpenWrtDocs/Hardware/Mikrotik/RB532

DD-WRT Support in dd-wrt is not good. There is an old beta.

CF layout

Kamikaze fits in a 16MB flash so any old CF card will do for booting.

Ethernet ports

There are three, the one to the left of the serial port is eth0 To the right are eth1 and eth2

By default in Kamikaze eth0 is in DHCP so it would make a good WAN port

Miscellaneous configuration notes

Password

Root password set from the console port command line using "passwd". Set to the usual root password.

Network

I hand edited this config file to create three networks. Should be possible to do it all from the GUI but maybe that did not work back when I originally set it up.

The WAN interface has its MAC address overridden so that it uses the same MAC as the old D-Link router. That way switching back and forth between the RouterBoard and the D-Link should not cause our Comcast DHCP address to change.

Note this did not work -- maybe I have the syntax wrong in the file? I had to go into the command line and override the setting like this 

ifconfig eth0 down
ifconfig eth0 hw ether '00:0D:88:5F:E8:90'

It loses the settings when I reboot, so I am ignoring it for the moment. We have a new IP address, darn.

Route command

Adding a default route so that you can get the webif stuff running initially; you need to add some packages. 

route add default gw 192.168.123.254

Packages added

After getting webif running I use it to make these package additions/deletions. 

etherwake
ntpd
openvpn
tcpdump
wol
nbd's QoS scripts

Packages removed 

ppp
ppp-mod-pppoe

DHCP

We provide DHCP only to the DMZ zone. 

/etc/config/dhcp
config dhcp

        option ignore   1

DNS

dnsmasq is installed but I am not currently using it.

I put this in /etc/resolv.conf so that it will use Kilchis to resolve names. 

nameserver 10.127.32.27
domain alseageo.com

Dyndns

There is a DynDNS tab under Network in the GUI. You can install and configure dyndns service.

Another way to do this is via ddclient on Kilchis, which is currently disabled. It used to run once per hour from /etc/cron.hourly/ddclient.

The config file for dyndns on the routerboard is /etc/config/updatedd: 

config 'updatedd'
       option 'update' '0'
       option 'service' 'changeip'
       option 'username' 'alseageo'
       option 'password' 'ice9viva'
       option 'host' 'members.dyndns.org'

Firewall

Set up from WebIf. Note that the rule names cannot have spaces in them 

config 'defaults'

NTP

Set timezone to US/Pacific Set servers to {0,1,2}.pool.ntp.org

NOTE: The standard WebIF ntp client has been removed from the GUI package manager.

I enabled the ntpd like this: 

cd /etc/rc.d
ln -s ../init.d/ntpd S99ntpd

All I had to change in ntp.conf was to add a rule allowing our 10.x.x.x clients.

cat ntp.conf 

# use a random selection of 8 public stratum 2 servers

QoS

Install but not configured yet. I'd like to use this to control bandwidth used for offsite backups. I want full utilization at night and 200 Kbps during business hours. A way to switch it down to a low bandwidth manually would be good.

SNMP

Installed but not configured yet. Could be set to log to Cacti on Kilchis

SSL

Installed MatrixSSL so that we can connect to router using a secure connection.

Syslog

Set to log to Kilchis. 10.127.32.27/514

Wake-On-Lan

Installed not configured

VPN

OpenVPN

Installed package. Not configured yet.

Set up

Support for the RouterBoard in OpenWrt seems to be pretty good, they have the latest releases prebuilt for the RouterBoard.

Install took 10 minutes including opening up the case. OpenWrtDocs/Hardware/Mikrotik/RB532

Support in dd-wrt is not good. There is an old beta.

Reflashing with OpenWrt X-Wrt

http://wiki.openwrt.org/OpenWrtDocs/Hardware/Mikrotik/RB532

The simplest way is to download the CF image file from http://downloads.x-wrt.org/xwrt/kamikaze/ and then use 'dd' to copy it to a CF card, then put the CF into the RouterBoard and off you go.

Get the 128k image. The 128k refers to the block size in the filesystem and it's good for CF cards.

Use the 'dd' command under Linux or Macintosh to copy the image to the CF card. Cygwin includes a 'dd' command so if you are burdened with Windows you can still use dd. I did not get it working and ended up simply usng Linux. YMMV http://www.groupsrv.com/linux/about17777.html 

dd if=/dev/sdb of=backupimage.bin
dd if=openwrt-rb532-jffs2-128k.bin of=/dev/sdb

The backup image is 256MB because that's the device size. Wastes some disk space but then again I delete it as soon as the RouterBoard is up and running again.

On my Macintosh with a USB card reader the command is almost the same, Macs are pretty cool actually. 

sudo dd if=openwrt-rb532-jffs2-12k.bin of=/dev/disk1


Configuration as gateway router

To-do

  • Fix routing table
  • dyndns updates
  • ntp server? (client is working) (ntpd is installed)
  • QoS
  • netmeeting - use dmz
  • dmz - allow OpenVpn access ?
  • WiFi -
  • DHCP for LAN?
  • OpenVPN
  • Scheduled QoS control?
  • Crow? or similar
  • WoL

Serial console setting

Connect a serial cable and use "screen /dev/ttyS0 115200"

Password

Root password set from the console port command line using "passwd". Set to the usual root password.

Ethernet ports

There are three, the one to the left of the serial port is eth0 To the right are eth1 and eth2

Network

This is the /etc/config/network file, hand edited to create two networks. There is a third etherport port (eth1) that is currently unused. 

config 'interface' 'loopback'
        option 'ifname' 'lo'
        option 'proto' 'static'
        option 'ipaddr' '127.0.0.1'
        option 'netmask' '255.0.0.0'

config 'interface' 'wan'
        option 'ifname' 'eth0'
        option 'proto' 'dhcp'

config 'interface' 'lan'
        option 'ifname' 'eth2'
        option 'proto' 'static'
        option 'ipaddr' '192.168.123.254'
        option 'netmask' '255.255.255.0'

Route command

At the console, add a default route through the old router (bellman) so that you can get the webif stuff running initially; you need to add some packages. 

route add default gw 192.168.123.1

Update resolv.conf

search wildsong.biz
nameserver 192.168.123.1

Packages added

After getting webif running use it to make these package additions/deletions. Dependencies are shown in parentheses. 

asterisk16-sounds (asterisk16, libncurses, libopenssl, libpopt, librt, libpthread, zlib)
asterisk16-chan-iax2

etherwake
ntpd
openvpn (kmod-tun liblzo)

NTP

Set timezone to US/Pacific Set servers to {0,1,2}.pool.ntp.org

Add this line to ntp.conf 

restrict 192.168.123.0 mask 255.255.255.0

Add link to /etc/rc.d so that ntpd will start, you can do this in webIf services page.

QoS

Install but not configured yet. I'd like to use this to control bandwidth used for offsite backups. I want full utilization at night and 200 Kbps during business hours. A way to switch it down to a low bandwidth manually would be good.

SNMP

Installed but not configured yet.

SSL

Installed MatrixSSL so that we can connect to router using a secure connection.

Syslog

Set to log to Bellman.

Wake-On-Lan

Installed not configured yet

VPN

OpenVPN

This end will connect with AGI's and keep the connection nailed up. I suppose I could also allow access back in from the world at large but that is not my primary objective.

So I do the usual - copy the config files from the AGI server and then start it up.

Phone server options

These are available as packages for OpenWrt

  1. Asterisk 1.4, 1.6 - a pain to debug configurations
  2. FreeSwitch - B2BUA/media gateway
  3. kamailio
  4. OpenSER 1.0.1-1 - Outdated version, it's called OpenSIPS now
  5. OpenSIPS 1.5.3-1 - SIP Proxy

FreeSwitch is divided into many packages. I am installing it on the system that I have been running Asterisk on, so that I can try it out on a real computer.
