We've got a linux VM (redhat 4.5) web server running with 2 nics running on a HP BL460C host with two physical NICs (also running on Redhat 4.5).
1 nic (eth1) is used for administative purposes so we can reach the machine from within our network.
The other nic (eth0) is configured so the webserver can be reached from the internet.
After rebooting only the first nic seems to work properly. I can reach the server from our network.
The http website cannot be reached. It looks like the request is coming in, but the response is sent to the other card.

After using the command "/sbin/ifup eth0 1" to bring up the second network card the website can be reached, but making a connection to the server from our network is no longer possible.
eth0 is bridged to vmnet0, which is attached on the host to eth1.286 (VLAN)
eth1 is bridged to vmnet1, which is attached on the host to eht1

We have a similar setup on another machine, same version same software, same config, but that seems to work quite allright!

It seems like there's a routing issue. Anyone familiar with this problem?
