Ok, that is progress though.  At this point we know that the OS is 
receiving the packet and Asterisk is listening on that interface and 
port.  I know you already removed the firewall so that would not be the 
issue.  My next guess is Asterisk is looking at the packet and dropping 
it because it believes it is not meant for it (Kamalio config issue), so 
try a simple test to confirm this.  Just configure a remote IP 
phone/softphone via that same VPN interface to simulate a remote SIP 
endpoint.  If the SIP phone works fine but Kamalio does not, that will 
clearly tell you where the problem lies.
