I cannot access http://www.dkpsystem.com/ or my guild's website at http://ep.dkpsystem.com/ using Firefox 2.0.0.1 on Vista.

IE is fine.

Any ideas?

Eeeeenteresting. I have no explanations.

I have the same problem. Any computer in the building running XP can get to your site fine using firefox. Any computer using Vista cannot.

I can't even get to your site using IE7 from one of the 2 vista computers, but from the other one IE7 works fine, but slow.

Obviously not a routing issue, as we all present to the internet as having the same IP. Also, if I fire up anonymizer (a proxy service) then firefox can access your site fine. I have also tried this using 3 diffrent ISP's with the same result.

It certainly seems to be a Vista problem, or a firefox on vista issue, but your site and the guilds that use your system seem to be the only sites I can't get to using vista and Firefox.

I have been able to verify that some others are having this issue too. The common denominatior seems to be Vista. Some CAN access your site using IE7 and some cannot. Firefox is a definite no go though. I have not found anyone that has Vista and can access your sites through firefox.

I also tried hitting it just using CURL in PHP on my Vista machine where IE7 Does work, and it just times out as well. I have not tried any other browsers.

Alrighty. Thank you. I'll see what I can uncover. It's quite bizzare, I have no idea what would cause Vista to fail to work with the site.

Thanks,

i have been digging into this off and on for about a month and a half. Only recently did I realize it was not just a local routing issue (I hadn't thought to try it from a non-vista machine on the same network, and the only machine I tried IE7 on was the one that didn't work).

Sorry Chops, but I'm actually glad to see other people having the same issues as I thought it was all me for quite a while.

I would be interested to see if there is anyone out there that is running Vista and ISN'T having trouble getting to these sites using Firefox. So far I haven't found any, but my sample size is small (The initial OP here, me and one other on the firefox boards that also says he can't get to your sites)

What I find especially wierd is that IE7 works on one of my machines, but times out on the other. The other fellow from the firefox board also can't use IE7 but the OP can.

Good luck

I just picked up a copy of Vista (just for you). I'll be installing tonight, and HOPEFULLY I get the same problems you are.

Vista is installed, and I've verified that it does not work with Firefox. Wierd. Now to the troubleshooting.

It turns out it's the firewall that's killing it in Firefox and Vista. I have no idea what about the firewall config is causing it, but I'm on it. I can't exactly disable the firewall for obvious security reasons, but I'm definitely working on a fix right now.

It will be fixed quite soon.

BINGO!

Give it a shot from your Vista Machines. I think I got it sorted out. It's working from my new Vista Machine now.

COOL!

That seems to have fixed it. Can you tell me what it was in case I run into it again? PM or email would be fine, just really curious about what firewall setting was blocking only Vista/firefox http requests (and occasionally IE7)

Sure. The server runs OpenBSD and uses it's built-in firewall pf. The problem was that each "pass in quick" rule didn't have "keep state" in it.

So my http rule, for example was:

pass in quick proto tcp from any to any port www

Fixing it was a matter of changing the rule to:

pass in quick proto tcp from any to any port www keep state

I don't know why that would only cause problems in Vista and Firefox (and occasionally IE), but not other machines, but it was also causing problems with SSH (I had to remote into another machine, and remote into dkpsystem.com from that machine).

In any case, "keep state" is a performance improver (one that I happened to miss when putting together the firewall rules), so I'm happy for two reasons.

Thanks for fixing this. I really appreciate it!
