MikroTik RouterBoard RB532A

RouterBoard 532A

In DNS, it's called OpenWRT and can be reached via ssh or https://openwrt 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.

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/7.09/

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

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.

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

MAC numbers

• eth0 00:0c:42:10:1c:6c
• eth1 00:0c:42:10:1c:6d
• eth2 00:0c:42:10:1c:6e

Miscellaneous onfiguration

Password

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

Network

Putting the D-Link mac address assures we wull get the same IP address assigned by Comcast.

Dyndns

Installed changeip client.

Firewall

Not set up yet.

NTP

Set timezone to US/Pacific Installed client.

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 Do a MARK every 20 minutes.

Wake-On-Lan

VPN

L2TPns

Have not looked into this one yet. Package is installed.

OpenVPN

Installed package. Not configured yet.

PPTP
