I have a very frustrating issue with win2k3 network configuration.
I have a dell PE1950 server with dual nics. 1 nic is on address 192.168.10.10, mask 255.255.255.0 default gateway 192.168.10.1 ( the cisco firewall vlan address) this interface is 1:1 natted from an external internet address.
The 2nd nic is on 192.168.210.10 mask 255.255.255.0 default gateway 192.168.210.1 (another vlan address on cisco firewall)
Both nics are on a l3 switch on different vlans and the .1Q trunk port going to the cisco firewall.
The first nic is to handle all external web traffic and be isolated from the internal data network. the 2nd nic carries all data from the internal servers.
Problem..... intermittiently good old win2k3 drops one of the gateways. it maybe a hour a day a week before it does this. I understand that win2k3 only likes to have 1 default gateway (after I have dug around) but can you use persistant routing to force 210.0 traffic out of the other nic rather than using the default gateway. I have tried setting up routes but nothing seems to work.
if I re-add the gateway address after windows drops it - everything works again.... for while.
I'm sure you can do this or are dual nics just for redundancy rather than true split networking ?
Many thanks in adanve
