[OpenSIPS-Users] SIP REGISTRATION behaves differently for LAN-based and web-based opensips

I have a test setup with two VoIP clients using OpenSIPS on a LAN and it
works fine i.e. I can make calls. However, when I move the server onto the
Internet the SIP REGISTER request fails with "408 Request Timeout".
I know that the Internet server gets the SIP request as I can see the
transaction counter increment using opensips monitor. The client also gets
the 408 response so it can't be a NAT/Firewall problem.
My LAN uri looks like <sip:voip1:password at 192.168.1.30>
My Internet uri is the same except that the IP address is the Internet
server's IP address.
Could it be something to do with the fact that I am simply using the SIP
server IP address in the REGISTER message instead of a domain name?
