I am having a problem configuring access lists to allow only certain traffic to forward through my two ethernet interfaces on a Cisco 2514 router. I planned to configure it loose at first and then tighten it up.
Here is what I have tried.
config t access-list 101 permit tcp any any eq telnet exit access-list 102 permit tcp any any eq telnet exit int eth1 ip access-group 102 in exit
I can now telnet from a host on the network attached to eth1 to a host on the network attached to eth0
Next
config t int eth0 ip access-group 101 in exit
Now I can no longer telnet from a host on the network attached to to eth1 to a host on the network attached to eth0
My question is what do I need to do to allow only telnet from hosts on the network attached to eth1 to hosts on the network attached to eth0 and vise-versa?
Thanks,
Tom Naves
