I putted in NAT both external and internal lan interface
Only interfaces used to go to internet should be on NAT box.
SOLVED PARTIALLY. Thank you iulyB. I set only the wan interface as NAT and not WAN and LAN. Now the VOIP and INTERNET access are OK using port forwarding for sip and RTP but I created the problem accessing from internal to internal server using pubblic address or domain. This problem didn’t existed with internal and external interface in NAT. It is an open problem if someone want to help https://www.zeroshell.org/forum/viewtopic.php?t=5746&highlight=
