Routing With 2 NICs

[Jim]

Hi,



I have a problem with a slightly old set up, but I want to find a

solution....have an XP Pro box, SP3, with two network cards.



Card 1: this is my internet bound connection and has a public address on a

255.255.255.248 subnect. The gateway is a Cisco router and this connected to

the internet without issues.



Card 2: this is an internal private address and is connect to another

internal network - just configured with IP address and subnet - no gateway.



I have installed nating on the NICs, card 1 being public (full) and 2 being

private. My network connecting on card 2 can get out on the internet by

specifying the card 1 address as the DNS server and gateway (have a DNS

service running). Nating was configured using the netsh command.



My problem is that I need to add a second address to the first card, this

will be a 192.168.0.0 /24 address. Doing this cuts the connection from the

network on card 2. Is this possible? I want to add this second 192.168.0.0

network on that switch on that card 1.



I am thinking that maybe this is not going to work and I need a third NIC in

this box. I know this sounds a bit backward....there is a reason for it

though.



Thanks

Jim
