Please read a tutorial or several. CGI Help Guide and Ovids web tutorial might be good places to start.

The actual issue is probably related to the firewall, not perl but your explanation leaves a little to be desired. We don't want to see all your code. 10 lines that demonstrates the problem is all that is required. By the time you distill the problem down you have often solved it, if not you have a far better chance of getting it fixed.
