I set up two asterisk servers (on Fedora) in different networks. My goal is to make a call from softphone (on windows lite with ip: 192.168.20.3) to the asterisk server 2 which is in the other network (ip:192.168.10.2).
But the problem is in registration between the two asterisk servers which are behind NAT.
NAT IP for Asterisk Server 1: 100.100.100.100 NAT IP for Asterisk Server 2: 200.200.200.200
Architecture:
IAX.conf in Asterisk server 1:
[general]
autokill=yes
externip=100.100.100.100
localnet=192.168.10.0/255.255.255.0
nat=yes
register => zone1:[email protected]
[zone2]
type=friend

Registration state: Rejected
NOTES:
- PING between the two networks is ok
- Firewall on servers was turned off
