Hello
I´ve tried to make VOIP to function for some time now through our Checkpoint VSX R80.20 gateways now with no luck.
Useing Hide NAT works just a littlle for awhile and then it stops working, that is audio in one direction only. So we want to use Static 1-to-1 NAT.
There are two resons why Hide NAT is not a option:
1: it does not work properly.
2: our ISP does not support the VOIP solution if we use Hide NAT.
I was told by our former contractor that the IP Networks we are NATing to has to be on an Interface in the firewall. So ringt now we have 2 interfaces towards the ISP one with the small linknet that we use today and another one with our /14 Static NAT IP Range.
We have both interfaces set to external. But I cant get any client traffic through and back, however from the GW cluster its possible to ping from the /14 interface to the ISP.
Is this setup even supported in the Checkpoint world?
