DFL-800 SIP Call
« on: December 01, 2010, 10:14:10 AM »
I have a DFL-800 with

Firmware Version:    2.27.02.11

Public IP:
93.xxx.xxx.xxx

LAN net:
10.0.0.0/24
LAN PBX: 10.0.0.226, GW 10.0.0.254

SIP Registrar and Provider 217.xxx.xxx.xxx

I have used and configured the SIP-ALG to connect with my SIP PBX to my SIP Provider.
Registration at the SIP Provider goes OK (UPD Port 5060).
If i start a call from intern via SIP to public Network
my PBX sends Invite to the SIP Provider (UDP Port 5060) but the answer of the SIP Provider
is dropped by the firewall (also UDP Port 5060).

I have configured the SIP ALG with the example form the D-Link side.
Only rules i have configured else are DNS Relay to check Internet functionality.

If i use no firewall an gave an official external IP to the PBX the registration and also the call is
going well.

Has someone an idea or the same problem solved ?
