[Asterisk-Users] * behind NAT and local subnet

[Damon Estep]

I have an * box behind a NAT router (static NAT, port ACLs set up
correctly)

Most of the SIP users are on the local subnet with the * box, they work
fine

Take one of the same users off of the local subnet and come in through
the NAT router and these results;

 

The remote user can register

The remote user can receive calls

The remote user can get into voicemail ???? not sure why

The remote user can not place calls

 

The trace shows 407, proxy authentication required

Asterisk shows failed to authenticate user.

 

This is clearly NAT related as the same user works fine inside the NAT
with no config changes

 

Is there are a way to connect to an Asterisk server that sits behind NAT
without breaking the ability to connect form the local non-NATed subnet?
