I have ADSL and am using m0n0 1.1 on a soekris. My westell DSL modem is 
set to do bridging but can be accessed at 192.168.1.1 to get 
statistics.

I have a static IP of 209.xxx.yyy.78 that is assigned to the WAN m0n0. 
My LAN is 192.168.100.1/24. Both of these are in a cold and dark place 
that I never want to go. So when I need to access the modem to 
configure anything or access it, I cannot do so easily. M0n0 doesn't 
know where 192.168.1.1 is.

How would I have to configure m0n0 in order to access the DSL modem and 
still be able to use the ISP's routable IP?
