[Asterisk-Users] IAX Registration being lost

[Wiley Siler]

I would assume this is an issue of port forwarding too.  Without having
a statically mapped port forward from your firewalls external to the *
internal IP, the port can shift.  The answer I gave below should resolve
your problem as well.

Cheers,
Wiley

Speaking of this. Why is it that sometimes the port is shown as
something differente than 4569 on some hosts? For ex.

Host                  Username    Perceived             Refresh
State
210.80.176.12:22110    8990608214  1.2.3.4:4569             60
Registered  

And why that host changes port each time it reboots?
This is happening to one IAX box I connect to.. And it's a pain cause I
have to put the port on my dial and registry entries in order to
register on it or dial to it.

Why is that?

Tony,

Do you have port 4569 on your external firewall IP port-forwarded to
your internal IP on the * box?

You should create a port forward of the external eth1:4569 -->
192.168.100.183:4569

Assuming that you exxternal IP were something like 1.2.3.4, you should
see this when you run iax2 show registry.

Host                  Username    Perceived             Refresh
State
210.80.176.12:4569    8990608214  1.2.3.4:4569             60
Registered 

Thanks,
Wiley

Well, this is getting more interesting.  I started looking at this this
morning and realised that Asterisk had lost registration, yet my ADSL
connection has been up for almost 2 days - and it was working fine
yesterday.  Therefore it doesn't appear to be related to the IP address
changing.

I'm thinking it's more that the registration is lost for any reason
(such as an ADSL reconnect or the registration needing to be refreshed)
and it won't come back.  Get this message as before:

Host                  Username    Perceived             Refresh  State
210.80.176.12:4569    8990608214  <Unregistered>             60  Request
Sent

I tried a ping and a traceroute and both working fine.  An ifconfig just
shows the internal address (192.168.100.183).
