Layer 2 encryption between two wlan ifs

Fri Oct 06, 2006 9:49 pm

Dear all,

I have configured two rb500 (2.9.20 version) with the following topology:

SWITCH1- eth1 - RB500 - wlan1 --- wlan2 - RB500 - eth2 - SWITCH2

I have already configured them with bridging between eth & wlan on each rb500 as the following url states:

http://wiki.mikrotik.com/wiki/Transpare ... o_Networks

The ip address on the interfaces is only for management, there is no layer 3 routing protocol on these.
The only protocol running is layer 2 spanning tree protocol between the switches.

My question is how I can provide a layer2 encryption via this link in order
to provide secure transmission of data?

Regards

Spyros

if its all tcp data you can use a vpn tunnel..setup one as a l2tp or pptp client and the other as the server.

or use IPsec and tunnels..

If your only concern is to secure the data as long as it is travelling 'over the air' you could just use WPA(2) encryption on your wireless interfaces and be done with it. In contrast to VPN-based encryption technologies like IPsec or PPTP this would have the advantage that WPA does not use a significant amount of CPU cycles on the router, thus performance can be better.
