Re: [Asterisk-Users] NAT/SIP solution?
I've heard of this: http://sarp.sourceforge.net I have no idea if it will be of any help, but it's an interesting programme for handleing SIP over NAT.

Hi Stig, If you are able to run * on your NAT'd box, then I have come up with a work around (thanks wasim!!!) that will allow you to run an * box behind your NAT, and still recieve and make SIP calls. I haven't got the whole thing figured out yet in terms of extensions.conf (but I am working on that today, will post on my website later) but this is basically my configuration: <--TDM400P--> <*> <--IAX--> <*> <--SIP--> |-NAT-||FW| So basically the * on the GW machine which is also the NAT / FW box recieves the connection from the SIP remote end, then forwards all the traffic over IAX to the NAT'd * box. I just tested it, and it works fine! Once I get some more complex extensions.conf files setup, I will post them. Thanks, Leif Madsen. BTW: As for just passing SIP through SIP, I believe it's a limitation of the SIP protocol as the RTP ports are different than the connection port, whereas IAX is all the same port for everything (from what I gather) ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
RE: [Asterisk-Users] NAT/SIP solution?
I might be putting words into Stig's message but I think what he means to ask was the following scenario that causes problems: SIP --- NAT --- Internet --- NAT --- Asterisk Nikotel has a solution and one participant in thi list is doing a trial on a SIP/NAT router (claiming to be the first one in this realm). To answer Stig's question as I understand it: I don't think anybody is working on a solution in this list since the by-pass is to put Asterisk directly on the Internet with its own public-IP address.

RE: [Asterisk-Users] NAT/SIP solution?
There are several SIP aware NAT routers. Any Cisco router with a firewall load has SIP aware NAT. There is at least one other brand of SIP aware NAT router out there, but I don't recall the brand.

RE: [Asterisk-Users] NAT/SIP solution?
Leif: I take it that the * on the GW machine remains in the middle of the call between SIP and the Nat'ed *, correct? I also suspect that you will be using IAX over Ethernet (to avoid compression/decompression delays), correct? Great work!

I also suspect that you will be using IAX over Ethernet (to avoid compression/decompression delays), correct? Great work! You'd be correct. IAX is over Ethernet, and the GW machine which runs asterisk is the in-between man which talks to the remote end, and talks to the other NAT'd asterisk box. I have this working great now, all my voicemail is implemented again, FWD works fine, FWD Welcome line works again, IAXtel in and out, basically everything I had before. I figured out what my problem was before, the hostnames weren't resolving correctly, simply changed everything to standard IP address, and it all worked... sheesh! I hate when stupid things like that get in the way :) Now, off to fix the hostname issue.
