Auerswald VOIP in LAN behind Sophos XG 105

Hi Uwe Merkle 

What traffic connections are required for your specific VoIP device to function? This will determine what rules and policies are needed to be created on your firewall.

In most cases, you will need to configure a firewall rule to allow your device to communicate out to the internet to your VoIP provider, along with creating a DNAT rule to port forward VoIP traffic to your device.

For reference:

• Sophos XG Firewall: VoIP calls may drop or encounter poor quality
• Sophos XG Firewall: Session Initiation Protocol (SIP) Support

Hi FloSupport,

I did not notice your answer until today because I did not receive any mail.

The part with the DNAT rule was, what i was looking for. I will try that.

Thanks for your help.
