[Bridge] All Packets Dropped if IPtables are enabled!

Hi, 
 
I have a single bridge, working between two PC's for testing purposes. In rc.local if I stop "service iptables stop", the bridge works fine and both sides are getting pinged. 
 
But when I enable the IPtables it stops working, I need the iptables for filtering and to use with ebtables, any Ideas ?
 
Thanks, 
Fahim Akhter

You probably have DROP has a default policy for the FORWARD table.

Add rules to FORWARD that lets the traffic you need through the bridge.

For example:
iptables -A FORWARD -s <host1> -d <host2> -j ACCEPT
iptables -A FORWARD -s <host2> -d <host1> -j ACCEPT
