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.

WARNING:

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