Support for Yahoo Messenger
Netopia Firmware Version 8.6.1 provides Application Level Gateway (ALG) suppor t 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 inter face, other wise the 
connections will fail. There is no restriction as to the number of connections.
There is no user configuration required for this feature.
