PhilT Posted January 3, 2012 Share Posted January 3, 2012 I recently replaced my consumer level gateway router with a 1701 since then most websites load perfectly but ive found a few that dont load they just return a blank page sometimes with the right favicon after about 30 seconds. While this page is loading access to other websites slows down to a halt. Ive got the router (ip 10.0.2.1 255.255.255.0) connected directly to the nic of my forefront server (ip 10.0.2.2 255.255.255.0). Ive ruled out forefront tmg as the cause by connecting a client to the router with the same result. Some examples of websites that timeout (ive tried getting the ip address and browsing to the ip same rusult) paypal.com upc.ie gamefront.com live.com https://supportforums.cisco.com Im sure its just a configuration problem since im new to ios and used configuration professional to set it up.
