Use NAT/PAT! Surely you have a firewall between your home lab and your
Internet connection? If not, then create a loopback and make it the "ip nat
inside", and create a static NAT entry on the router that maps it to port 80
or whatever you can get "out" of your company's firewall on... Use an
access-class on the vty lines to limit connections to that port only.
Check the Groupstudy archives -- this has been discussed in the past, and
I've done the same thing to my lab in the past. Also, consider using SSH
instead of telnet -- unless you control the firewall (and it doesn't sound
like you do), then maybe you don't want everyone seeing what you're doing
all afternoon connected to that outside address... ;-)
Later,
Pete
