Some webpages not showing up

[phontanka]

I have a Jaht 2104G router and run 3 machines through that router, two with WinXP one with Kubuntu. Recently I've had a funny problem: some webpages didn't show up at all. On my two WinXP machines this problem was solved by lowering the security level to medium in ZoneAlarm, the firewall.

I tried to look at some ways to do this on the Kubuntu machine too, but I couldn't find anything. In the system settings there is nothing about firewalls.

My newbie question is: is there a firewall installed on Kubuntu by default? How can I make changes to its settings?

Has anyone got any ideas?

(PS I think there's still an issue with my router somewhere, but in a way the two xp machines work fine now)

Re: Some webpages not showing up

Kubuntu doesn't install a firewall by default, so no worries there.
There are many reasons why a page might not display in Linux. One reason might be that the web page is using Macromedia Shockwave. Unfortunately, there's no Linux version for a shockwave player, and you probably need to install Wine to have it.

What is the website anyway? Maybe I could check if it's loading here properly.

Re: Some webpages not showing up

Thanks for your info. This page doesn't need Shockwave, it's a simple html site. I knew that this site was ok because when I hooked my cable modem directly to one of the computers it worked perfectly, the page loaded. With the router I got nothing, so I thought I had a problem in the router. With the firewall settings changed, on the winxp computers I could load the page on xp, but still not on Kubuntu.

The funny thing is that right now the page loaded on Kubuntu too. So my problem is solved.
