This will be a really simple question to someone who knows what they are doing.
I've got a cisco 1801 with fa0 connected to a dsl router. I've assigned a valid public ip to fa0. I now need to connect some servers, all with public ip's in the same subnet as fa0 to the 8 switchports, and confure an acl on fa0 to only allow certain ports to certain public facing servers on the switchports.
I've configured fa0 with a public ip, configured a default route to point to the dsl router connected through fa0. from the cisco i can ping public ip's no problem, but when i plug a server into a switchport, i can't even ping fa0 from the server.
Should be a very simple config, i think?
