I have setup a LAN SER and everything is working fine. Obviously, clients being on the LAN, everything is direct IP and there are no NAT issues.

 

I am now trying to make NAT’d clients access the server. I know NAT and SIP together are full of problems, but since volume will be low I am considering simply using a proxy such as “fwdnat” for Free World. This solution is already tested and works properly in our test setup, using xten’s X-lite soft IP phone. We will consider migrating to full fledged “hard” IP Phones when everything is in order.

 

Can anyone tell me if this is the best solution for a small (< 50) company? What is the best way to setup access from outside our firewalls ?

Are there OSed proxies I can use with SER? Can SER itself be configured to act as that kind of proxy?

 

Thanks for all the info you can provide,

 

Daniel
