Restrict which programs Firewall allows to be run.

I am running Windows2000 server., connected to the internet via a router.

I would like to install a firewall to only allow the client logging in to be running my program on THEIR computer.  eg   client.exe

The client.exe program running on their computer will allways be logging in on port 1002., winsock.
My program client.exe has a login password  to the server which is encrypted, and the program is unable to proceed without verification.

Unfortunately i will also have to have access, from only my computer, using pcanywhere.

----

Which firewall program would you recommend i buy for this
situation.

----
Appreciate any help

My recommendation is a Cisco PIX, only because I am most familiar with it. It all depends on your budget, how many users will be accessing your application, and what else this firewall will need to do.
What kind of connectivity do you currently have? Broadband, DSL, Cable, T1? Do you currently have a router?

I would suggest Kerio Personal Firewall from www.kerio.com
This would give you the following.
1. ability to limit which programs on your machine can listen/talk on ports, to/from what addresses, and specify times of the day this applies
2. ability to reconfigure (1) remotely
3. ability to observe what ports are currently in use, by what programs, to what addresses
4. again, ability to do (3) remotely
5. ability to specify certain actions be logged, either to the local machine or to a third machine elsewhere on the network (syslog/udp support)
6. free trial (actually unlimited, but legally you are obliged to buy a licence if you trial for more than 30 days and are a "commercial" user)

anyhow, go download and try it. if you don't like it - well, it didn't cost you anything to try.

*lol*
Maybe lrmoore *does* deserve the points - just for the sheer chuzpa of "recommending" he is awarded them :)

Dave HoweSoftware and Hardware EngineerCommented:
lrmoore's third answer is certainly the most complete though - if suspiciously cut-and-paste looking - and worth the points.
