[mythtv-users] iptables not blocking traffic from MBE to SBE

[Mache Creeger]

I am having problems getting iptables to block traffic from my MBE 
(DIGIT) to my SBE (DEN). I have the proper iptables script in place 
but packets still get through. It has got to be something simple. 
What have I forgotten?
