Support for Yahoo Messenger

Netopia Firmware Version 8.7 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.

• For a simple 1-to-many NAT configuration (classic NAT or PAT), use the
