Comcast allocated a /30 for my WAN interface and a /28 for my network use. They are in different class C address spaces. Gordon Russell Clarke County IT I understand what you are trying to accomplish I think. Just as a stupid thought, could you simply setup virtual IP's for the addresses you are trying to use and setup 1:1 Nat and forward them to the internal servers. I understand this means you will have to use nat. You may be trying to avoid this, but it seems like a much easier solution. It also seems more flexible.
