Cannot access my websites

I have a really strange problem. I cannot access any of the websites I'm hosting at my Reseller Account. Actually I cannot access anything that is related to the server where my Reseller Account is (web sites, c-panels, reseller WHM, etc.), not through the web or FTP. It acts as it's going to connect and it just keeps on spinning till it times out.

What is strange is that this only happens from my home connection. I have no problem connecting from the office or from my brother's house (which has the same ISP) and everybody else can connect and see the sites (I've asked several friends to check from their home or work place).

I've pinged the sites and all 4 packets return fine. Traceroute resolves fine from home and office.

If I surf anonymously (through kroxy.net) i have no problem accessing any one of the sites, even from home.

Webhost and ISP have confirmed no blacklisting or any problems on their end and suggest I wait a couple of days for problem to go away?????

I'm lost here, so any help will be appreciated.

TIA

 

Interesting...how do I do this?

 

Thanks guys.

I've tried OpenDNS, as well as other similar servers, and the problem still persists.

My internet arrives via cable modem through a coaxial cable, so it cannot be plugged directly into the computer. I have bypassed the router and plugged the modem directly, but still not a solution.

It's not a computer issue because with my MacBook I can connect to me brothers WiFi and access the server with no problem.

I've provided my ISP and the Hosting company with all related IP's and both have not found any blacklisting.

From the office I accessed the WHM panel and all I found about Mod Security is that it was installed and active (as it has been from the beginning), but there was no option to view listings or anything else, or to deactivate/activate it.

ISP said they where going to send home a technician so I'll just have to wait and see.

 

Update - Problem Solved

Got tired of waiting so I went ahead and disconnected the cable modem for about a couple of hours, after which everything seems to work fine now.

I had initially unplugged and reseted the modem and started it right back, which should assign a new external IP number to my network. This didn't work so somebody suggested leaving it off for an hour or so, that way it might assign an IP number from a different range. Don't know if this is possible, but it seems tio have solved the problem.

Thanks everybody for their input.
