websites down

Hi all,

My websites are down and I can't figure out why. Everything was working with my old Internet connection last time I checked. The (new) Internet connection works fine; I can browse the web and even access the websites from the LAN but not externally. Externally it just appears like the web page is taking a long time to load but after a while it fails.Bandwidth is not the issue. I have tried yum upgrade and I have tried restarting the server and I have tried deleting the firewall rule allowing HTTP connections and setting it up again. I am using dyn,com for dynamic DNS so I thought that might be the problem but when I check the logs on dyn.com it says all is fine.

Any ideas on how to solve this?

Thanks.
