Default Server
This feature allows you to:
• Direct your Gateway to forward all externally initiated IP traffic (TCP and UDP protocols
only) to a default host on the LAN.
• Enable it for certain situations:
Where you cannot anticipate what port number or packet protocol an in-bound applica-
tion might use.
For example, some network games select arbitrary port numbers when a connection is
opened.
When you want all unsolicited traffic to go to a specific LAN host.
Combination NAT Bypass Configuration
Specific pinholes and Default Server settings, each directed to different LAN devices, can
be used together.

Creating a pinhole or enabling a Default Server allows inbound access to the
specified LAN station. Contact your Network Administrator for LAN security
questions.
