VOIP Fritzbox after Sophos XG

mario Andrick

Hello, 

i've got a  question about the configuration of my VOIP communication. 

 

Today i've got a new modem so my configuration is now like: 

Vigor 130 (DSL modem) --> nic1 of Sophos XG firewall --> NIC2 --> Internal Network --> Fritzbox (Voip Server). 

 

But i have very big problems with my phones. There is no outgoing connection. 

 

What Rules should I create in my Sophos Firewall XG? 

 

Thanks a lot for helping me

    Well, I solved it on my own.

     

    I updated to the latest labor formware 6.98 for my 7490 and made a factory reset.

    Now it's working out-of-the-box without any additional firewall rule.

     

    The AVM is now working as a client behind the XG and is only responsible for the SIP registration and DECT function.
