[Asterisk-Users] Incoming SIP or IAX2 via NAT

[James Nunnerley]

Thanks for the replies guys (Chris & Peter)...

I think I've confused matters by not explaining things properly!

My ISP has my internet connection on a private IP address - so my LAN has an
address (192.168.42.*) and my internet connection has an address 10.100.x.x.

That is then NAT'd again onto a single address used for a large majority of
their customers.  I won't go into the details of exactly why this is the
case, but I used to work for them, and they're still not charging me for the
connection, so I'm not complaining!!!!

I am going to move off it, but it will be a few weeks before I can... so...

Can IAX2 operate over double NAT?  If so, what do I need to put in the
register part of the config?

Cheers
Nunners

Can you login to the voiptalk control panel and change the numbers to point
at your current IP ?

Not sure what you mean by that. Surely if your box was receiving calls from
them before the IP change, and now isn't (on a different IP), then the only
thing that needs changing should be the IP on their control panel.

If that's not an option for whatever reason, your best bet might be to find
someone with an asterisk box on a static IP in a datacentre to which you
could get your voiptalk numbers pointed, and you could then have your box
register periodically with that box.

<shameless plug>as luck would have it, we have a few boxes that'd fit the
bill, contact me off-list if you want to discuss it further</shameless plug>

Regards,

Chris
