D-Link router preventing access to one site

[Shaotai]

Anyone know why I can't get to this site through my D-Link router?

My trusty DI-624 router will not let me get to this site. I disconnect the router, hook directly into the cable modem and it works fine. (Comcast)
I bought a new DIR-615 router, same issue.
Contacted D-LINK support, they had me change my MTU settings from 1452-1500 but none of them helped.
Not sure if other brand of routers would cause the same issue. I have no issues accessing everything else on the 'net...
Suggestions?

I have a DI-614+ and don't seem to have any issues.

You may want to look at your Filters and see if you're blocking certain IP's.

Another thing to try is to set the DMZ to your Computer's IP and see if you can get to it that way. I wouldn't want to leave it like this, as it by-passes the Firewall, but it's good for a test.
