Enable Media Proxy

To enable Media Proxy, you need to run the following commands in the server where dnl_softswitch is installed:

// Load the corresponding iptables modulels:
sudo modprobe iptable_nat ipt_MASQUERADE iptable_filter

// Enable FORWARD rule:
sudo iptables -A FORWARD -m conntrack --ctstate NEW,SNAT,DNAT,RELATED,ESTABLISHED -j ACCEPT

You can verify with the following commands:

[root@dnl~]# iptables -L 
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)
