Router not passing request to ISP for some IP's

Hi,

I have a strange issue in which my netgear wndr 4500 is not passing request to even ISP for some websites. Initially I thought the issue was with my ISP routing, but after looking at traceroute and mtr reports it clearly is an issue with the router and I don't have any kind of parental control or block sites feature enabled. I've also tried lowering the MTU, but doesn't help.

Please find MTR report for google (which works) and a website that doesn't work:

I'm really disappointed having spent so much money on this one as my 35$ D-Link DIR-524 Router works fine with both websites.

Any help will be appreciated, I've already done following:

1> Checked settings to see if any blocking functionality is enabled, parental control etc are all disabled.
2> Tried lowering the MTU as advised on a separate thread.
3> I use google dns and the hostname is resolving to IP just fine.


Thanks
