Hi,
I've installed ser-0.8.11 on FreeBSD via ports. Things run fine on a private LAN. I have setup a pp2p tunnel, which shows up as ng1 in FreeBSD's ifconfig. This allows Windows users at the remote end of the tunnel to see the FreeBSD box just fine. The pp2p tunnel runs over a NAT'ed, public IP address to another box which does the same thing.
However, NAT isn't (or shouldn't be) in the loop as the pp2p tunnel hides all this. The public internet looks like one p2p link. I've verified the above via tcpdump using many different applicationss.
Private addresses are used on both LAN's. Any box can see any box just fine. On one FreeBSD machine, I am also running SER. It doesn't seem to respond to the register SIP message. SER is listening ONLY to the ip address that corresponds to its end of the pp2p tunnel.
Before I dig into what I might be doing wrong, I'd like to know if the above is even supported.
Thanks, MikeC

Yes, it is supported (there shouldn't be nay problem if the packets reach ser). Try to dump the packets on the interface and see if they really reach ser. If so, enable debugging in ser cfg and look in the log for errors.

Thanks Andrei.
This helped a lot. Apache, various test socket applications etc. all worked. SER did as well.
I'm up now. I think the problem I had was that the IP address for the SER end of the pptp link wasn't in DNS. SER didn't think it was the destination, even though the IP address was the one ser.cfg had for "listen=". I added this IP address to the A record for the system and things worked.
I then added the other LAN interfaces to ser.cfg (the LAN that I tested my SER setup with earlier, before trying the pp2p link) and it too (still) works. Things look good.
Support for "tunnels" in SER is a fantastic feature. This is a great way to get around NAT for private office to private office connections.
Thanks, MikeC
