We are setting up a connection between our primary site and a replication site. I have setup a router at each site and they connect via a T1. I now have connectivity between the two sites, but I want to implement security between the two sites to limit the traffic that can go through. Can someone help me with the commands? I have no real experience with ACLs, so I keep cutting myself off when I try to create them. Here is the situation:
Network 1: 192.168.1.x (255.255.255.0)
Network 2: 192.168.9.x (255.255.255.0)
Router 1: 192.168.12.10 (e0/0)
Router 2: 192.168.9.10 (e0/0)
Anyway, I would like to limit traffic between the two networks via the following:
Two hosts on the 192.168.1.x network should be able to use TCP ports 3218 and 3682 for replication to the 192.168.9.x hosts. (The same goes for the other direction).
I want to also allow telnet, ping, and smtp from the 192.168.1.x network (and the router itself in .12 network) to the other side so I can manage the router and send notifications.
Can someone tell me how to get started with the commands?
