Natting

We have a customer who is running pbxnsip (Version 2.x) in LAN. He has natted the private IP to a public IP and opened the ports on firewall. The Snom SIP phone (on public IP) is trying to register to pbxnsip using the natted IP as registrar. We can see the register requests coming to pbxnsip and pbxnsip is giving an error "send packet 404" as below

 

Resolve destination 122033: a udp 210.212.206.117 5060

Resolve destination 122033: udp 210.212.206.117 5060

Send Packet 404

 

What does this indicate? The ports are open bi-directional. Still we dont see any request reaching the phone.
