traffic not getting through virtual firewall
Posted on 2009-07-10
I've been trying for some time to repair a virtual firewall to allow traffic through to our internal network. To give you a little background we have a dell power edge server running windows 2003 64 bit. The machine has 3 NIC cards, 1 is directly attached to our Comcast modem and it has the VMware bridge protocol enabled. The other two cards are tied directly into our local switch. 1 of these 2 has the bridge protocol enabled and the other is for the host machine. We originally had 3 virtual machines running. 1 windows 2003 SBS server, 1 Endian firewall community server and 1 Linux based spam filter all working in perfect harmony.
I say it was perfect until we switched internet service providers. For some reason every since I updated the ip info within the Endian firewall we have not been able to get traffic to pass through. I have tried rebuilding the firewall, I have tried replacing the firewall with other solutions such as smoothwall and ipcop, all with no success. I even tried upgrading the software from vmware 1 to vmware 2.0.
The adapter configuration for the firewall is as follows:
the green interface is set to bridge mode and the red interface is tied in to VMnet4 which is bridged directly with the NIC that is connected to the Comcast modem,
Im pretty confident it doesn't have to do with the firewall configuration itself. The reason i believe this is because I was able to bring up a virtual windows xp machine, assign the adapter the external IP info and RDP directly into the machine over the wan. I could be wrong on this estimation and am open to any suggestions you have to offer.
