Sophos firewall

[athena]

Hello,

I'm trying to configure NAT on Sophos firewall, but I cannot pass the firewall check...
There is still a port translation, but I'm unable to find how to configure one-to-one NAT.

Did someone already configured a Sophos with 3CX ?

Thanks in advance for your help.

Have you open up the required ports - http://www.3cx.com/docs/firewall-router ... tion-voip/

The ports are open, but the problem is the static port forwarding (static NAT).

How can I configure it on Sophos UTM to avoid error message :

Testing SIP Port 5060 using STUN server: stun.3cx.com:3478
Resolving STUN server stun.3cx.com ... Resolved to: [198.50.247.220]
[Test1] Reachability test ... FAILED.
Internal port number (5060) does not match external port number (58248)

How can I configure the UTM to avoid this unwanted port translation ?

Hi,

If it exist, please turn off "SIP ALG" or something like that in the Sophos UTM
