Assuming that eth0 is the external interface and eth1 is connected to the receiver, then

1. Disable eth1 in NetworkManager

2. In rc.local

• In SL, Centos (redhat clones)

ifconfig eth1 <ip> pointopoint 10.0.9.54

• In Debian

ifconfig eth1 <ip> pointopoint 10.0.9.54
route add -net 224.0.0.0 netmask 240.0.0.0 dev eth1
