Pinholes

This feature allows you to:
• Transparently route selected types of network traffic using the port forwarding facility.
FTP requests or HTTP (Web) connections are directed to a specific host on your LAN.
• Setup multiple pinhole paths.
Up to 32 paths are supported
• Identify the type(s) of traffic you want to redirect by port number.
Common TCP/IP protocols and ports are:
See page 82 for How To instructions.

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 application 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 sta-
tion. Contact your Network Administrator for LAN security questions.

IP-Passthrough

Motorola Netopia® OS now offers an IP passthrough feature. The IP passthrough feature allows a single PC
on the LAN to have the Gateway's public address assigned to it. It also provides PAT (NAPT) via the same
public IP address for all other hosts on the private LAN subnet.
