I've setup just the IPADDR= and NETMASK= to have different static IPs in
different subnets and changed to the BOOTPROTO=static in each of the
ifcfg-brX scripts.

This hasn't fixed my issue. Perhaps it's because of the way I'm trying to
use it (or I don't get it). Does each VM that is using a specific bridged
device need to have the same IP subnet as that of the static brX address?

What I am trying to accomplish here is this:

Router (192.168.7.1) ---------> eth0/br0 (10.1.10.1) -------------> VM01
(with internal vr0 and vr1 attached to br0 and br1 and a bridged IP of
192.168.7.253, running Untangle in bridge mode)

VM01 --------> eth1/br1 -----------> local switch -------------> eth2/br2
--------------> other running VMs.

Thinking that the internal bridging done by the Untangle VM might have
caused an issue... I setup just a stock Win Server 2003 install with a
single ethernet device attached to br0 and set a static IP in the
192.168.7.X range (in Win 2k3 VM). The untangle VM is shutdown. I still
can't ping 192.168.7.1 from the Win2k3 VM.

Thanks,

Jacob
