Pass Through-

The DI-774 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-774. This is useful when you have many
VPN clients on the LAN network.

vice (DDNS) feature.

network
connectivity.
