I'm intending to use iptables on CentOS 6.5 for all Freepbx (Asterisk) output via eth1.

I have two network interfaces:

eth0 - > internal network (for connecting PCs with the softphone)
eth1 - > internet (All Voip Out)

The rule: iptables -A PREROUTING -i eth1 -t mangle -p tcp --dport 5060 -j MARK --set-mark 1

I want to direct SIP to eth1 only, but I'm not successful

iptables

You need to route beyond the 5060 registry ports, also the RTP ports, otherwise you will only authenticate but will not pass audio.

Asterisk uses port UDP by default, so unless you have changed the transport of SIP signaling to TCP, this may be the problem.

In addition, asterisk uses a range of high ports for audio / video traffic: 10,000 to 20,000 UDP, and you need to create rules for this range as well.
