Allowing access through a Firewall?!

Hey guys,

I've recently been delving into the world of setting up my own webserver... just for fun like.

Anyways, I've setup an old machine running apache under windows XP and can access it fine from the web as long as I have zone alarm turned off, but the second I turn Zonealarm on I can't access the server (for http only on port 80).

On my router I have port 80 forwarded to the server, would this mean that people trying to access on any other ports would be blocked? If that is the case, does it mean my server is safe if I turn off zonealarm?

Obviously I'm concerned about the security of my network and don't want people to get into other parts such as my main machine. Any advice at all would be appreciated!

Thanks muchly.

Wow! I just had this issue... a minute ago. I fixed it, came online, and here's your question. :eek:

For HTTP serving, go into Firewall > Main > Internet/Trusted, and hit "custom". From there you may specify ports and ranges to allow.

My problem was more with connection sharing, though:

Go to the Firewall section of ZoneAlarm, hit the "Advanced" button in the lower-right corner (you may have to enable "custom advanced settings" somewhere first), and select the option, "this computer is an ICS/NAT gateway" under the Internet Connection Sharing heading. (Not sure if this applies to you.)

If I wasn't very clear, blame it on ~15 hours of sleep over the weekend, and let me know. Smiling

Kewl... Do I really need Zone Alarm on though? My router only allows connections through port 80 and has an onboard hardware firewall that prevents DoS attacks n stuff...

Thanks for the Zone Alarm info though I'll check it out!

I've been a bit low on sleep this weekend too! Must be a techie thing!

Hm, if you have levels of firewall and filtering already, then I don't see a need for ZoneAlarm either.
