Airport Extreme blocking access to websites

Sorry to ask but... did you try just restarting the Base Station by pulling it from power for a moment?

The Airport Extreme N base station with gigabit ethernet ports is part number MB053B/A in the UK and MB053LL/A in the US.

By the way - are your web sites being hosted on a server located on the internet outside of your LAN, or on a server located on your own LAN (ie inside of the Airport base station)?

Do all of your computers have this same problem? Has anyone else reported problems accessing all your web sites?

I am having a very similar problem. After WEEKS of troubleshooting, it's been determined that my Airport Extreme BLOCKS access to twitter.com. If I connect directly to my cable modem, I'm good. If I go back to my old cheap (and slow) Netgear router, I'm good again. Airport extreme? Can't resolve to twitter.com no matter what. So far, this is the only domain I've run across with this problem. I even tried the domain's IP address without success.

Is there a way I can manually configure my Airport Extreme to stop this nonsense??

Hi,

I just posted this to another thread but anyway I think I found solution to this problem. For some reason since last update Airport Express gives me automatically different DNS servers than what I get straight from my cable modem. I'am not network specialist but I guess it's some sort of proxy-dns inside router... No idea. Anyway the solution was to go Airport Utility -> Manual Setup -> Internet -> and manually write your ISPs DNS servers there.

If you don't know your ISPs DNS servers, you can connect straight to your cable modem and look the right IP addresses from System Preferences -> Network. I hope this helps!

I have the same problem here and nope, putting the ISP DNS servers and domain name into TC/AP doesn't fix it here. 😟

Oddly enough, after leaving my network quiet for about 7 hours overnight (but NOT powered down), when I woke this morning, all of the sites that my TC had been blocking yesterday are now working. Weird! This wasn't a reboot issue as I have 5 active systems on my net and all had the same access problems to the same specific sites.

I have recently noticed that I'm unable to access certain websites also. The one in particular site I have been unable to access is http://dev.cmsmadesimple.org/ I have also not been able to login to my Microsoft Messenger application either, I usually use a Jabber address so I can collate everything in iChat but no joy from that either.

From memory the only things that have changed since I last logged in to my MSN account are as follows:

• Airport Extreme Base Station Firmware upgrade, now running 7.3.2
• Purchased and installed AppleTV
• Software updates installed for 10.5, but I hadn't restarted until after the problem surfaced

I have attempted reverting my ABS firmware back to 7.2 still no joy. Disconnected AppleTV from the network, again no joy.

I'm not sure what other routes to persue, and advice would be much welcomed. My supplier is Virgin Media up to 10MB option, if that makes any difference.

Thanks

Just a quick amendment, I have tried a couple of things to try and narrow down the possible culprits, although I'm still confused. I have tried accessing the Messenger application from an old PowerBook running 10.4, and that can't log me in either. I then went back to my G4 and booted up VirtualPC, running XP and I have been able to login using the XP Live Messenger application, but still can't access the http://dev.cmsmadesimple.org/ site. Not too sure where that leaves me now.

Me again, I have now been able to access the site I was trying using http://anonymouse.org does this mean anything to anyone, does it make it more obvious as to where the problem may lie?


Thanks

Im having the EXACT SAME problem. all of a sudden today (I did not even update OS nor the AE firmaware), my AE will not route to ONE IP address. if I do a traceroute to one IP above and/or below, it works fine.

I tried to hard-reset AE, did not help.

again, this is only ONE IP address that I can get the router to route out to. same IP I have been accessing in the past no problems.

anyone has a solution to this?

I spoke to Virgin, and after an hour or so convincing them it definately wasn't my hardware that was at fault, the suggestion was to hold tight and wait. A couple of days later something had changed and I was able to access the site I wanted. Not much of an answer here other than the fact that it was all out of my hands.

it has to be the AE blocking or not routing to that IP address. as soon as I switch to another router, I have no problems. its only when the AE is in the chain that this is happening. hence, its definitely an issue with AE.
