Configuration of Router with multiple IP addresses
Posted on 2012-03-26
We have a BTBusinessHub router - "2Wire Gateway", model 2701HGV-C which came with our Total Broadband. We also had a single static IP address. Everything was working correctly.
Since we want to run SharePoint and other services (on several VMs) we ordered 8 static IP addresses (5 of these are usable a.b.c.161, 162, 163, 164 and 165).
After two or three calls to BT, we are wondering if the Router is up to the job. BT say our router is not capable of supporting NAT (but say we can still use it) but on the user interface it appears to show mappings between internal and external IP addresses. However, we don't seem to have full control.
Issues 1: The router gave one of our servers an external IP address but the internal IP later disappeared!
Issue 2: It wouldn't allow us to set an external IP address on another server, despite allowing the router's DHCP to issue the IP address.
So the question is, do we need a different router or has someone succeeded in making this router work in a similar environment - if so how? We think this is a very typical environment. Any advice welcome - thanks.
