Cannot connect to server!

[Jeremy Hein]

I am currently not able to connect to my rh8 linux box to sshd or httpd through port 22 or 80 from a remote location! It is behind a checkpoint firewall that only passes traffic through those ports. It was working before. The only thing I believe I changed was installing webmin. I've disabled all firewall services that I can think of and verified that I can connect locally. Any ideas on how I may be able to troubleshoot this? Are there any services or config files that may have been changed without me knowing it?
