I’ve searched and found this thread on how to access my DSL modem but it’s not working for me. http://forum.mikrotik.com/t/how-to-access-external-router-via-wan-port-on-rb750/56317/1
As a new MikroTik user I copied and pasted a firewall from their wiki to get started and I’ll paste it here in case what’s blocking my access can be found there:

MikroTik IP is 192.168.2.1
Bridged DSL modem is 192.168.1.1
Can someone explain what the code listed in the above post is doing? Any idea why it’s not working for me? I can plug directly into the modem and assign my laptop an 192.168.1.xxx IP and get into the DSL modem but it would be nice to access it from the 192.168.2.0 network.
