need to fix freepbx nat in dmz using opnsense / pfsense

Hi, we need a professional Asterisk / freepbx sysadmin who can fix the nating in dmz using opnsense.

currently we have done 90% of work

Lan 192.168.X.0/24

WAN A.B.C.D (static public)

DMZ 192.168.Y.0/24 PBX is here (also VIP to L.M.N.P public IP) using 1:1 Nating

now the odd thing is that we are using linphone as softphone and we are having problem while being both client outside over 3G etc.

calls on the lan are fine. and if one client is on 3g and the other on lan its also fine.

but very common we get one way audio if two clients are outside.

pls make sure you can fix this, as we dont have lots of time for delivering it to work
