I'm currently trying to setup my network to allow access to my lab from the internet so I can play with it in my downtime while at work.
My network is using the 192.168 address range and I have e0 on my access server (2509) assigned to this range so that I can get to it from inside as well as route ports to it from my cable modem.
I'm trying to set up an ACL on the access server to deny telnet connections back out of the e0 interface to any other computer on the inside network. Specifically, I want to block access to my mail server port 25 via telnet.
Everything I have tried thus far still allows access to the server from the router. Any suggestions?
