the DI-764 supports VPN (Virtual Private Network) pass-through
for both PPTP (Point-to-Point Tunneling Protocol) and IPSec
(IP Security). Once VPN pass-through is enabled, there is no
need to open up virtual services. Multiple VPN connections
can be made through the DI-764. This is useful when you have
many VPN clients on the LAN network.
