I am running a ubuntu 13.04 machine with the follow:

3 interface: 1 external(eth0) 2 internal(br1 br2)
services dhcpd, bind, samba..etc
VM running win7 using the virtio drivers bridged to br1.

Since I installed the firewall I am unable to get anywhere from the VM to
the internal network. All other services appear to be working fine such as
 I dont yet have the external network connected to anything as I am trying
to make sure things work before replacing the current firewall.

I de-installed the firewall and everything started working. I reinstalled
and again it appear to not be happy.

I did a bunch of googling and can't find anything that matches up to what I
am doing. Any ideas?  I can post whatever config need be.

# Specify here your internal network (LAN) interface(s). Multiple(!)

INT_IF="br1 br2"

# Specify here the internal IPv4 subnet(s) which is/are connected to the
# internal interface(s). For multiple interfaces(!) you can either specify
# multiple subnets here or specify one big subnet for all internal
interfaces.
# Note that this variable is mainly used for antispoofing.
