Re: Using applications on server

Using any Winsock application on the ISA itself is fraught with issues,
because many of them use complex protocols and work best when the FW client
is installed on their host.
Since you can't install the FW client on the ISA (actually, you can; it's
just a really bad idea), that limits you to packet filters for those apps.
WMP uses TCP-1755 and UDP-1024-5000 for MMS protocol, so that makes for a
screaming buttload of PF to create.
ISA wasn't designed to operate in the contexts of a workstation, so there's
little support for doing that.

Hello Jim,

This I know, however I want these apps to run behind the firewall, but
not clog my own machine up - that way I can do important stuff without
losing performance on my own PC.

I should point out that I am fully aware of making sure that shared
directories only contain files I want other people to see. I also
normally clean all files out of my shared directory at regular
periods.

I'd also like to be able to run media player on my server so I can use
it to listen to internet radio stations - however, I can't - it won't
connect. Anyone have any ideas ?
