I think I am the person you are referring to  :)

I don't remember the exact procedure (and I don't use the router any more), 
but here is now I got my Linksys router to send data via SNMP:

In the router configuration page, I set it to send "log information" to my 
computer (using internal IP of the computer). I then installed a program 
called "snmptrap" and "linksysmon". 

Linksysmon uses snmptrap to "trap" data sent by the router, and write it to a 
log file. While obtaining the outside IP was not my goal (I have a static 
IP), I did see somewhere in the linksysmon manual how to enable some hidden 
options in the router, allowing it to send it's whole syslog-like output, not 
just the connection log. Using this option, I remember seeing my external IP 
mentioned (obviously it never changed).

Again, I am not sure how to extend this solution to other routers.
