I'm working with a company with the following network - AT&T DSL internet access through a Netopia 3347NWG router serving DHCP to about 25 workstations; 192.168.1.0/24.
They're getting a Netscreen firewall that is supposed to come pre-configured with a visible outside IP address, let's call it 220.127.116.11 which is would be an outside ip given us by AT&T.
Is it possible to set up the Netopia to allow traffic to 18.104.22.168 to pass through directly to the Netscreen interface using the 1 DSL line? The AT&T technical support couldn't seem to help but I expect I never made it to their A team.
Clarification: I'll have 2 outside IPs coming to the netopia. One (22.214.171.124) will be going exclusively to the netscreen while the netopia will handle everything else. I'll need the netopia to continue the DHCP duties as well.
