IG7600 Administration Manual

Note: When do you need this function?

If IG has a public IP for remote EXTs to reach there is NO NEED to use NAT Traversal.

When IG works under the public network, and has a domain name, there is NO NEED

to use NAT Traversal either.

Sometimes IG works behind a router, M54 can only reach to IG through the router

with the IG’s domain name. We have to tell IG the Router’s external IP Address if we

have a static one. As below:

If the Router does not have a reachable static external IP Address, we have to enable

NAT Traversal to make sure IG knows the Router’s external IP address. And ask the

router to do Upnp Port mapping to make sure IG is reachable for Remote parties. The

Stun server and the TURN Server are for you to deal with these circumstances. In

most cases Stun server is used, TURN Server is more capable when the client

supports ICE, since M22, M62 and M54 doesn’t support ICE, we’ll not give you any

examples.

The UPNP port mapping is to tell the Router that packets to these ports should send

to your IG, it makes no sense when your router opens DMZ to your IG, because all

packets are surly sent to your IG.
