3cx full cone on XG 135

Hi,

you would only need a mask rule because the 3cx will setup the connections. What is firewall rule and please include detail port lidtings.

Hi Ian,

thank you for the reply

Here we are:

3CX_TCP includes

3CX_UDP includes

Hi Stefano. I also run a VOIP PBX behind my Sophos XG.
One incoming NAT rule, one outgoing rule. 

Hi Peter thank you are you using a 3CX PBX? if yes your firewall check on the 3CX interface is all green?

No i do not use 3cx

Solved....

i have only a problem with the port 5060 but i think that is the FrtizBox modem the responsable...i have already open a support ticket.

Anyway, to solve the problem, i had to delete and rebuild the DNAT rule

You might like to review your port 5060 configuration, you have it twice TCP and UDP, the 5060 to 5060 is not required.
