How come I can't ping my home computer?

Question

I'm trying to set up a vpn into my home computer in order to access files from wherever. I have the home computer set up with a no-ip dynamic dns program so I can always connect, and have also tried using the actual ip address. However, when I try to connect or even ping from anywhere outside of my house I can't get through. I've tried putting that particular computer in the dmz, turned off the computers firewall and anti-virus, and I still don't get anything. I have comcast as my home internet provider. I have also tried from two different locations. Are there any other solutions I can try or is comcast the issue? I used to be able to do this when I ran a small web server at home for fun but now nothing works. Thanks in advance for any suggestions!

Solution 1

You can try plugging your computer directly into your modem without going through the router and testing the ping. If it works then, you know it is a router issue. If the problem persists, check your firewall (sometimes Norton/McAfee/etc have hidden firewalls running).

As far as I know Comcast would not block pings.

Solution 2

Make sure you computer is setup to reply to pings. In order to give you a more complete answer you would need to post your operating system.

Ya I'm retarded. I dug into the settings on my home router and found a setting that blocked pings. All good now, so now I'm off to figure out if my vpn will connect. If not, that's a whole other issue. Thanks for the help!!!
