I have a silly question. I'm planning on taking an SFP handoff from my carrier and plugging it directly into a Catalyst L2 switch. Now, in the past they have given me circuits with an IP address of 1.1.1.1/30 and had a block of IP addresses "riding" on that circuit. For instance, they would give me a block like 5.5.5.0/28. So, normally I'd plug that directly into a router and do NAT to expose my internal webservers and whatnot. Now I have a scenario where I want to use external addresses for a few servers. My thinking was to plug the servers into several ports along with the SFP handoff from my carrier and put all those ports in the same VLAN. But I was thinking no one could access the 5.5.5.0/28 network if I gave the vlan interface the IP address of 1.1.1.1/30. Is this true? So, what I wanted to do was just give the VLAN interface an IP address of something inside that network such as 5.5.5.1/28. But then it seems the IP addresses would be lost because they couldn't get to 1.1.1.1/30. What can I do in this situation besides add a router to the mix? TIA.
