Some of these rules require coordination with the unit’s embedded administration ser- vices: the internal Web (HTTP) Port (TCP 80) and the internal Telnet Server Port (TCP 23).
Internal Servers
The internal servers are the embedded Web and Telnet servers of the Gateway. You would change the internal server ports for Web and Telnet of the Gateway if you wanted to have these services on the LAN using pinholes or the Default server. Pinhole configuration rules provide an internal port forwarding facility that enables you to eliminate conflicts with embedded administrative ports 80 and 23.
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
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 Games and services and Default Server settings, each directed to different LAN devices, can be used together.
