I have a problem accessing any web site that start with 64 as the first ip address. I can't ping the web site or do a trace route..doesn't get past the router. Can't type the ip address in the browser window and make it work. Our provider recently put our network on a different ip address (we are linked through a wireless bridge to the ISP) we are now using an IP address beginning with 64 also. I have set our 3620 router to the new cahnges..just can't access anything beginning with 64. Any ideas out there. I think the problem may be on the ISP side,but don't really know. TIA

Sounds like a routing problem where all of your requests for the 64.x.x.x network are routed to your local network. Either that or a misconfigured firewall.

I agree with Rockn. More specificaly check that you netmask on the router is not set to 255.0.0.0 . For most networks the correct setting is 255.255.255.0 .

Might be worth a call to your ISP just to verify the mask. If they are a smaller one, they may be using variable length subnets, in which case your mask could be just about anything.
Is there a firewall between your network and the router? If so, try telneting into the router and try to ping. If you can ping from there, the problem is definitely in the firewall, if not, the problem is in the router or further downstream.
