Tim,

  I can connect to it from my location (IF) I connect right after I disconnect after having connected from his node to me via ssh. I see this bidirectionally on the tcpdump on his system. If I then disconnect and try to connect from another location or this same location later I see nothing on tcpdump and I get -

[Jan 11 00:20:36] NOTICE[9224]: chan_iax2.c:4071 __auto_congest: Auto-congesting call due to slow response
    -- Hungup 'IAX2/71.185.222.180:4569-697'
    -- Hungup 'Zap/pseudo-546901569'
    -- Hungup 'Zap/pseudo-1177483345'

at my end.  I really think this is a router issue. The router has been reset. Not sure where to go from here.  Is there a setting on this router for persistent NAT?

This is node 29971 at IP 71.185.222.180

Do a “tcpdump port 4569” at the Linux command line and incite a connect from another node. You should see inbound packets.

I have seen ISP’s block port 4569 but not FiOS. I’m on FiOS with an actiontek router and it works fine.

I am remotely trying to troubleshoot a friends new Allstar installation.  I can ssh in and connect out to nodes but I cannot connect in to the system from external nodes. Port 4569 is forwarded.

I discovered this link -

http://www.voip-info.org/wiki/view/IAX

about consistent NAT and I was wondering if that might be the problem.

I was able to connect in one time right after a reboot which might support the NAT issue.

The router is an Actiontek MI424WR GigE  as supplied by Verizon on their FIOS system.

Is anyone else having a problem with this router or have any ideas on this? 

Nothing is logged at the server or shows up in the client on the system which kind of points to a routing failure.

Is there a good way to check for open port 4569 as I don't think normal port scan programs will check this.
