Sip Registration showing Public IP vs Internal IP

[mdt19572]

1. Brekeke Product Name and Version:
Brekeke SIP Server , Version 3.0.7.0/333 Standard
2. Java version:
1.6.0_18
3. OS type and the version:
Windows Server 2008 R2
4. UA (phone), gateway or other hardware/software involved:
Zoiper
5. Your problem:

I have a subnet of 10.1.0.0 / 255.255.254.0

My server is 10.1.1.220 with "interface address 1" set to this as well.
My client(s) are 10.1.0.x

Under Registered clients I'm seeing my UA registered with my public ip address of the client network vs an internal ip address.

I'd like to keep everything on the internal network and assume I can do a Dial Plan to work around this but kind of lost on the syntax to use.

Thank You for any assistance.

It will happen because the SIP client detects its global IP address for the firewall traversal.

Tune the SIP client's settings to disable the public IP address detection.
It will be STUN or ICE in the settings.


If you capture packets at SIP Server's PC, are SIP packets exchanged with the public IP address instead of the internal's?

The packets are exchanged with internal but ends up with the external.

I've disabled STUN and it appears to be using the internal IP now, will test it out.

Thank You.
