I have a very simple problem that I can't resolve at the moment.
We have had an SDSL line just installed.
This only provides us with 2 public IP addresses. However, we have been given a range of public IP's we can use behind the first 2.
An SDSL router/modem has been configured in passthrough mode using x.y.z.157 as the external address.
We need a very simple router to sit after the SDSL modem with an external address of x.y.z.158 default gateway x.y.z.157 and an internal address of a.b.c.100. This will then be connected to our Cisco PIX which has an external address of a.b.c.99 and use port forwarding for our internal mail servers etc.
The problem lies in the middle router. No one seems to supply a simple router that has no firewall, no wireless - all I want is one external RJ45 and one internal RJ45.
