[Asterisk-Users] Asterisk Behind NAT

[C. Tomlinson]

I know this is possible using IAX easily, although I guess that is not an
option for you.

I have no firsthand experience, but believe some have got it working via
careful setup e.g noreinvites and other things.

If you setup a linux router, you could maybe have a separate DMZ to the *
box, but still use QoS?

Hope someone else can help you.

Best of luck with the new job.

Hi all,

I've done quite a bit of reading, and I see that it's going to be 
difficult, but as a last-ditch effort before implementing a suggestion 
I don't like at all, I figured I'd ask...

Has anyone successfully put an asterisk box on an internal network 
behind a NAT device and been able to connect with SIP from outside?  
The real point behind all this is to implement QoS for the voice 
traffic, and putting a third box in front of the asterisk and NAT boxes 
has been deemed "too expensive".

Currently, asterisk has a public IP, as does the NAT box behind which 
all the office machines sit.  If it can be done, the NAT box would be 
the best place to do the QoS, so why not ask, right?

Alternatively, I'm open to any suggestions that would work.  I've been 
handed this challenge on my first day on a new job... :/

Thanks,
