[Asterisk-Users] IAX - Registration Problems

[Bartosz Wegrzyn - asterisk]

Hi everyone,

THis is my second thread regarding the issue.(before I was having problems
with accessing my email, which slow down my responses, sorry for that)
My setup looks like this

Firewall
|
|
Asterisk---Asterisk (two asterisk servers with the same  setup for high
avail)
|
|
phones

Ports 5060, 10000-20000, 4569, 5036 are forwared to 192.168.1.251 which is
virtual ip address on one of the asterisk servers. (the one that is
currently running)

The real ip addresses of the asterisk servers are 192.168.1.253,
192.168.1.252.

When I try to use the softphone like firefly with SIP everything works fine.
But, when I switch to IAX then the client can't register.

I was trying to register using the 192.168.1.251 which is virtual Ip.
When I change it to real server IP, then I was able to register using IAX.

I know that IAX is a very friendly protocol.
I am planing to use it so clients can connect to my asterisk box from
outside through my firewall. Why the Virtual ip is causing the problems.
My ifconfig output looks like this:

eth0      Link encap:Ethernet  HWaddr 00:01:29:94:34:2E
          inet addr:192.168.1.252  Bcast:192.168.1.255  Mask:255.255.255.0

I turned the iax debug to find out more.
This is the output when clients tries to register:

voip*CLI>

when I change the ip to 192.168.1.252 the output looks like this:

Looks like the password is missing in the first transaction.
Any ideas why???

I would like to move on to running iax throuh nat, but so far I am unable
to make it running locally.

Thanks
