3-6 Firmware User Guide
Support for Yahoo Messenger
Netopia Firmware Version 8.4 provides Application Level Gateway (ALG) support for Yahoo Messenger. This
allows Yahoo Messenger users to exchange files, even when both users are behind NAT. Previously, the file
transfer function would work only if one or neither of the two users were behind NAT.
Currently there is a restriction that the remote user must be routed to via the WAN interface, otherwise the
connections will fail. There is no restriction as to the number of connections.
There is no user configuration required for this feature.
MultiNAT Configuration
You configure the MultiNAT features through the Telnet menu:
• For a simple 1-to-many NAT configuration (classic NAT or PAT), use the Easy Setup Profile configuration,
described below.
• For the more advanced features, such as server lists and dynamic NAT, follow the instructions in:
• IP setup, described on page 3-7
• IP profile parameters, described on page 3-21
Easy Setup Profile configuration
The screen below is an example. Depending on the type of Router you are using, fields displayed in this screen
may vary.
The Local WAN IP Address is used to configure a NAT public address range consisting of the Local WAN IP
Address and all its ports. The public address map list is named Easy-PAT List and the port map list is named
Easy-Servers.
