Do you really want to do that?
Do you want to connect a client that's on your internal network to an
Internet service provider, tunneling a PPP link through your firewall?
That sort of hoses any protection that you might get from the
firewall.
Now, what's the difference between that and connecting to MSN,
CompuServe, or AOL? Without having access to that client's source, (or
putting a sniffer between teh client and the remote server) you really
don't know what's going on there, and you might very well have a
client on your network sending information up the pipe to one of these
guys, or sending stuff down the pipe, in the form of downloads and
installs that run in the background...
Further, if you do have a problem with what's going on, are you going
to be able to get prompt and useful cooperation from responsible and
clued people on the other side? If a virus starts to propagate around
all of your PeeCees, how are you going to deal with it? Whom are you
going to call to find out what could have happened?
(Do you think I'm making all of this up? It was rumored a while back
that Compuserve's client had a hidden feature that allowed the client
and server to switch roles, which the developers put in without the
knowledge or consent of anyone else. I heard this from someone who
used to work there. I asked some CompuServe people about it, and
they'd neither confirm nor deny this feature's existance.)
