[Asterisk-Users] Xten and NAt Problems

[Chad Brown]

I would recommend looking at a relatively inexpensive product by Ingate which provides both near-end and far-end SIP NAT traversal.

If you have a firewall they have a product called the separator. Otherwise the have a good firewall that will do the trick. Both solutions need the "Remote SIP Connectivity" module.

Besides that, how would you make * work for sip if for example this:

Softphone - nat - internet - nat - *

Why? What you did doesn't accurately simulate someone on the outside trying
to get through your firewall because you are passing through it twice and
many NAT rouiters won't do this. It's called "hairpinning".

Look up NAT router hairpin on google, there is some interesting info on it.
