Hi all! I'm trying to configure ser to work with all clients behind a nat. I know fwd use ser + asterisk. I noticed that if I have a client behind a nat in fwd I have to set an "Outbound Proxy" (in Xlite for example). The FWD Outbound Proxy is fwdnat.pulver.com:5082. I noticed that there is a "ser" at fwdnat.pulver.com:5082.
Why fwd use an outbound proxy and another "ser" at port 5082 instead using default ser at port 5060? I have to configure 2 distinct ser to solve nat problem or can I use unique ser at port 5060 with nathelper? Using another "ser" as outbound proxy at another port is better? How can I configure ser to be an "outbound proxy"?
Thanks you, Aldo.

This is, apparently, because some customer routers and firewalls try to do things to SIP packets and if you run it on port 5082 then it avoids that problem.

You can use an unique one.

No, it's not better. All your users behind NATs would have to configure their UAs to use your special nat-traversal outbound proxy. You don't have to configure anything special in ser to act as an outbound proxy (but you have to configure your clients).
