I have a small problem with my VPN connection, It's up and running but I 
can't ping the other end, I get traffic from the other end in form of:

22:17:56.114188 192.168.5.2.netbios-ns > 192.168.5.255.netbios-ns: NBT 
UDP PACKET(137): QUERY; REQUEST; BROADCAST
22:17:56.863179 192.168.5.2.netbios-ns > 192.168.5.255.netbios-ns: NBT 
UDP PACKET(137): QUERY; REQUEST; BROADCAST
22:17:57.612417 192.168.5.2.netbios-ns > 192.168.5.255.netbios-ns: NBT 
UDP PACKET(137): QUERY; REQUEST; BROADCAST

but when I try to ping I just get:

22:20:06.082020 arp who-has 192.168.5.2 tell 192.168.5.1
22:20:08.093102 arp who-has 192.168.5.2 tell 192.168.5.1
22:20:10.103089 arp who-has 192.168.5.2 tell 192.168.5.1
22:20:12.113091 arp who-has 192.168.5.2 tell 192.168.5.1
22:20:14.123231 arp who-has 192.168.5.2 tell 192.168.5.1

5.1 Is the system on my side and 5.2 is the remote system, everything is 
working perfectly otherwise and i have opened up my ipfw config to an 
allow all from any to any just to test it out.

The system worked fine and then someone pulled the plug from the server 
and now everything is back up and working except the traffic over the 
VPN, what could I be doing wrong?
