[Asterisk-Users] SIP client registration ignored by Asterisk

I have an xlite client registering with asterisk. The client is on a
separate subnet routed via a site to site VPN tunnel to the subnet
hosting the * server, with no active firewall between the subnets.

With one IP address (192.168.3.56) set on the client the * box ignores
the SIP REGISTER request. 

Ethereal logs on both sides of the link show the REGISTER packets
arriving at the * box, but no response. With the problem IP address the
client can PING, SSH and Telnet to the * manager port successfully and
can connect to the web service on the * box.

Changing the IP address (192.168.3.99) of the client immediately lets
the Registration complete successfully.

The problem has persisted through several reboots and through a
stop/start of the Ethernet interface.

Verbose asterisk output (level 50) and sip debug shows no activity
whilst the packets are ignored, and a search of /var/logs/asterisk files
gives nothing to indicate a problem

Debug output from the xlite client (below) illustrates the problem and
the immediate connection upon changing client IP address.

I have reviewed previous postings but cannot find any pointer to the
root cause of this.

Does anyone have any previous similar experience or thoughts as to the
possible cause?
