[OpenSIPS-Users] NAT issues on client and server

[Mark Currie]

Hi Stefano,

 

Thanks for your interest.

 

There is no private network such as a VPN being used. I am testing using a
virtual cloud server in a CaaS environment which puts it behind a NAT
firewall (although later the server may have a fixed IP address). The
clients are currently simple console apps (based on Baresip) operating on
PC's behind a NAT/firewall on a LAN. Later these clients may operate on a
mobile phone, in which case the cellular network will be NAT'ed.

 

Currently, the only mods I have made to the default OpenSIPS (Vers. 1.6.4.2)
config file is "alias=<server IP address>" and fix_nat_register() related
mods. However I actually get quite far with these mods as you can see from
my dialog below.

 

Network architecture:

Server = Ubuntu 10.04 LTS server with OpenSIPS 1.6.4.2
