I have been trying to figure this out for a while, hopefully someone here can help me out.
I have a Public class C. I want to take a /27 and route it through a VPN tunnel to another location so that other location can use the public IPs. I have Cisco 2811 Routers at both ends.
I can setup a site-to-site VPN connection on the routers but its figuring out how to route the traffic through so that the /27 comes out on the other end and the machines that communicate on the other end come out using the /27.
/27Subnet --> 2811 <VPN> 2811 --> Hosts
Hosts --> 2811 <VPN> 2811 --> /27 Subnet
Bidirectional communication. I can use internal 10.x.x.x subnet if needed to route between them, and I was thinking of setting up some sort of NAT, but not sure if it will work.
Anyone have any ideas on how to accomplish this? Thanks in advanced.
