Passing public IP's through a Cisco router?
Posted on 2004-11-29
This question pertains to having the ability to use public IP addresses on machines connected to the "internal" port of a 1760 Cisco Router.
Here's my problem: I have two servers that utilize public IP addresses. Right now they are connected directly to the MPOE through a hub, and from the hub a firewall sits between the MPOE and our internal network. I now have in my posession a cisco 1760 router that has a T1 CSU/DSU card connected to a NEW T1 service that we will be migrating to. I have one public IP address assigned to this "serial" port, and one private address assigned to the internal "FastEthernet" port. I use NAT PAT all the time on our firewall to punch through web services, etc... But I've never attempted "punching through" a static IP address... Is this possible, or am I dreaming?
