[Asterisk-Users] iax2 registration problems

[Bartosz Wegrzyn - asterisk]

On the asterisk1 I got this:

register => username:secret at ipaddress2

[eop]
username=username
secret=secret
type=peer
host=ipaddress1
auth=md5


on the second box I got this

this host is ipaddress2

[incommingiax2]
username=username
type=user
secret=secret
host=dynamic
context=from-internal-custom
auth=md5


on first host 1 am getting:

Jun 22 14:42:10 NOTICE[2398]: chan_iax2.c:7411 socket_read: Registration
of 'proxy1' rejected: 'Registration Refused' from: 'ipaddress2'

if I enable debuging I got this:

Tx-Frame Retry[000] -- OSeqno: 000 ISeqno: 000 Type: IAX Subclass: REGREQ

Why the box is refusing the registration.
That box is on DMZ vlan with local ip
On the pix firewall public ip address2 is mapped to that box ip

debug on the second box

any ideas what could be wrong?

Thanks
