No UPNP/NAT-PMP, no STUN! How can i make calls between two NAT?
my scenario like this: PHONE1->FS (192.168.0.4) -> NAT1 (Public IP 1.2.3.4) -> INTERNET -> NAT2 (Public IP 5.6.7.8) -> PHONE2 (192.168.1.100) First, I have forwarded sip port and rtp port. I have try servaral configurations in http://wiki.freeswitch.org/wiki/General_NAT_example_scenarios and without luck! PHONE2 only regists to FS, how can FS gets through NAT2 to PHONE2, include sip signaling and rtp connection ?
Hello arliyardo, I'm new to Freeswitch, but looking at the posts on the mailing list it appears a few of us - you, me and Vladimir Elizarov, have been grappling with he same thing recently - getting remote phones to work through NAT. If you look at my thread you will see I have got some of the way, and can call incoming now but still have difficulty with outgoing calls. Perhaps you might have a look at where I have got to and see if you can think of the final bit of the picture? I gather the developers are in the process of updating the Wiki pages on NAT. I'm hoping they will be able to find time to continuw with this. It must be a laborious and time consuming task keeping the documentation up to date. bests Bruce On 11 March 2010 01:25, arliyardo <arliyardo@gmail.com> wrote:

The key here is that you have two devices that can totally mess with your SIP and RTP: NAT1 and NAT2. What are these two devices? Secondly, what kind of phone is PHONE2? Some phones work better than others. Third, have you captured the SIP traffic behind each NAT device to see what's going on? You won't be able to fix the problem until you actually find out what the problem is and where it is happening. For the record, I've done this kind of thing using X-Lite and Snom 300's as the PHONE2 in your example, so I know it is possible. The trick is making sure that your NAT devices have their SIP ALG's turned off. Check this page to see if you have one of these devices: http://wiki.freeswitch.org/wiki/ALG
