[Freeswitch-users] registration fails after several hours - FS problem?

[Mario]

I really need help on this as I have weeks into this problem. I thought I had it nailed but I guess not. After 5.5 hours I get:
2010-10-25 15:05:43.407272 [WARNING] sofia_reg.c:387 mguuid Failed Registration, setting retry to 15 seconds.

and no way to make/get calls until I restart FS. I did this:
1. log 7
2. sofia profile xxxx siptrace on   for each profile/gateway
3. restarted router

All three did not solve the problem. The trace and log produced no additional lines which is why I am wondering if FS has a problem since the trace shows no SIP activity.

3 gateways with 2 ITSPs
2 DSL/WAN lines, 1 static and 1 dynamic
I am using autonat:1.2.3.4 in internal and external profiles. 1.2.3.4 is the external static ip.
sofia status profile ... has the right ext ip
nat_map status shows the dynamic (wrong) IP
I tried starting with -nonat but that was worse
the only way to fix is restart FS.

I read the wiki on external nat, auto_nat and everything else many times.
Thanks Mario
