Hello all

My apologies if this has been asked before but I can's see anything using a search.

We have just had our 1MB business service installed by NTL (35 days late!) and we have a Samsung cable modem. Our service includes 5 IP addresses which, very stragely, are not contigious.

The firewall has multiple IP addresses allocated to the network card and we will be putting public facing machines on the DMZ with private addresses and the relevant ports forwarded. The auto registration process will only allow us to allocate one of the IP addresses to the MAC of the firewall.

Does anyone know of a way round this please?

NTL help desk suggest putting a hub/switch on the cable modem and our other machines on this. What's the point of having a firewall if we do this or should we find a firewall that has 6 network cards?

Any help appreciated.

Andrew
