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?
