Yes. You can install an snmp daemon on your Linux box, which will make it
respond to snmp commands a router would respond to as well. I don't like
this approach because my 8MB 486 router didn't have enough memory to run an
snmp daemon concurrently with mrtg.

The second way, which I like a lot better, is to have mrtg call an external
program which then creates the right numbers. Very easy to do:

 export PATH=$PATH:/usr/sbin
 ipchains -vx -L output | grep $1 | cut -b 9-19
 ipchains -vx -L input | grep $1 | cut -b 9-19
 uptime
 echo $1-router

This creates output mrtg can understand.
