Mike,

Okay, well last night I opened up that port for LAN to WAN (Internet),
and I still got dropped packets, so you have done a good job at explaining
why.  Therefore I also opened up 113 for WAN to LAN access, just in case
the client machine can fill the IDENT request.  However, most of our
machines are Win95/98/NT4.

Since last night, 7 to 8 hosts have tried to get to our LAN for these
services.

What exactly does the client tell the host, anyway?  Finger info?
