Airport Extreme problem. Certain websites not working anymore

[nizmoz]

I can't access certain websites anymore through the router. If I plug the PC directly into the modem it works fine, but through the router.

Any ideas how to fix this issue as the website I need access to is one that I edit and maintain!!

It really doesn't make sense that it would be the router. I can't even think of what settings would cause this. Possibly DNS..are you using your ISP's DNS? If so try using Open DNS and see if it makes a difference.

I moved the DNS from open DNS to google's public one and it made no difference. It is definitely the router but question is what.

Do you have a proxy configured? Have you tried multiple browsers?

No proxy. All machines can't access it. Event my iPad while on the router. Works fine on other networks or straight into the modem.
