Dual NIC's in one PC - Internet & LAN

[MikeFCS]

Hi,

I have a Dell Preceision 960 with two NICs installed.

The first NIC is an integrated Broadcom NIC and I want to use it for
Internet and remote access via web. The TCP/IP is set for auto IP and DNS.

The second NIC is an Intel Pro 1000/GT which has 4 virtual NICs setup on it.
One for each VLAN that have their own IP, Subnet and gateway defined in the
TCP/IP config.

The VLANs to the Intel come off a Cisco switch in a closed network with no
internet access.

The input to the Broadcom comes from a different hub that has internet access.

I can get internet access through the Broadcom if I "disable" the Intel in
the Network Connections window but then I lose the data tracking to the apps
while it is disabled.

Typically when the Network is connected through the Broadcom it has an auto
assigned IP of 10.0.0.13.

The VLAN IP's, subs and gw's are:

VLAN 90 - 192.168.42.108, 255.255.255.128, 192.168.42.1
VLAN 91 - 192.168.42.140, 255.255.255.192, 192.168.42.129
VLAN 92 - 192.168.42.208, 255.255.255.192, 192.168.42.193
VLAN 93 - 192.168.67.10, 255.255.255.192, 192.168.67.1

I need both to play nice so I can keep the VLAN apps running and be able to
get internet and remote access (via VPN) when I need it.

Thanks,

Mike

I think this is a multihomed computer with two default gateways, which is
not recommended. This search result may help too.
