2 NICs on internal network

By kevin ·
I have a netgear firewall protecting my overall network which assigns 192.168.0.x addresses to two servers one linux the other NT4.0(SBS4.5).

What I want to do is to put 2 nic's in both these machines and pass that traffic through a firewall on each machine. I can do it OK with the Linux machine but the NT machine will not let me activate the firewall on MS Proxy 2.0.

My internal/internal IP range is 10.0.0 - what am I doing wrong?

Thanks in advance.

KP

Hi,
Do you have IP Routing enabled in TCP/IP advanced configuration? Without this enabled, NT does not know to route traffic from one nic to the other.

Hope this Helps!

Hey,
Check this article out. It seems Proxy 2.0 does not like DHCP on the external interface.

Hi Howie - the IP address is pre assigned no DHCP. The configure internet hardware wizard runs ok. But when I click security I get an error saying there is no external nic on this server so I can't use packet filtering. Funny thing is I have to select internal lan card and the card that is connected to the Internet. Does it look at the IP address range as I have assigned the 192.168 range - my router is the internet gateway.
