Firewall Question

[TechBoyJK]

I'm running SQL, COldfusion, php, and IIS, and was curious about something. If I blocked everything incoming except port 80, would all of this still work?

Depends on what people need access to from the outside. If all they do is hit a website, and your webserver pulls from SQL in the background (assuming the webserver and the SQL box are both behind your firewall) then blocking everything except port 80 should be fine. Keep in mind though that if you use HTTPS you'll need to open 443 too.

Best thing to do is to test it from an outside source and find out.

I second Bosch's assesment. If you're just using these services to run a webpage then only having port 80 open should be great. Is the server only going to do webpages or is it going to host other services as well? Such as email, DNS, Terminal Services, etc? These will each require other ports to be open.

thanks, I just wanted to confirm that if I only need port 80, that I can get away will simply blocking everything else.
