   I finally solved my problem. It was a routing problem.   
   The PCs i tried to reach must have a default gateway pointing to the Zywall   
   to send the pings back to the vpn client. Kind of basic for most fo you i   
   guess   
   but you learn the hard way everyday.   
      
   The Zywall must also have a default route to send whatever he doesn't know   
   as destination address,   
   which is the case for a roaming pc, to the next router on the internet.   
      
   It wasn't firewall related but a routing problem.   
      
   The problem i have now is telling the PCs to direct the usual internet   
   (http, ftp and mail) traffic   
   to the former LAN gateway (a win2000/ISA server) and direct only VPN traffic   
   back to the second gateway (Zywall).   
      
   I just solve a problem to face a greater one it seems.   
      
   Could any one help ?
