Hello,
Here are the details:
Host: running Ubuntu 7.10 with 3 NICs eth0 is naturally binded with VMNet0
VMWare Server 1.06
Guest: Ubuntu JEOS with two dedicated NICs. eth1 is binded with VMNet2 and eth2 is binded with VMNet3
The project is to create an inline IPS (intrusion prevention system) in bridge mode with EBTables, and multiple application. It's not worth explaining the rest since it does not go further.
STEPS: Once the VM image is up and running and that the Jeos systems sees 2 network interfaces, we started building a bridge between the two nics. Doing so traffic is supposed to go through without interfering with it (called transparent bridging).
once bridge interface br0 is created and eth1 and eth2 are in the bridge, traffic is supposed to go through. MAC address are learned from the right interface but trafic is blocked somewhere. The same exact setup was reproduced on a dedicated machine with 2 NICs (meaning not virtual - no VMWare) and it worked perfectly.
Any hints anyone??
