No one can ping my IP Address & PC Anywhere Doesn't Work

by Daviddude / April 8, 2013 10:23 AM PDT

Hi CNET peoples,
Strange problem here, here is the history.
I have Time Warner / Roadrunner internet at my home. I was using a Linksys modem router for the internet and it wasn't the best of modems, it would lock up, I would have no internet until I power cycled the modem. PCAnywhere would work, I could connect to my home computer when I was away from home. I switched back to the Time Warner rented modem and yay, I have internet now but I can't connect to my computer via PCAnywhere. I have already done the pin hole in the router - a Linksys WRT54GS - and still PC Anywhere does not work. I can't even connect to my computer using my internal IP when I have my laptop connected. I have asked my friends to ping my external and they can't it always returns the error message of 4 packets lost 100% data loss. I have called Time Warner and all they say is "Can you connect to the internet? Yes? Then our job is done, contact your IT person for help". This makes no sense, on the other Linksys modem router PC Anywhere and pinging worked, but not on this set up. I have unplugged the modem, router, all computers for a day and powered everything back up, no change. I have already done the router reset, set up the pin hole again and no change.
Does anyone have any ideas?

Not a strange issue.

Since pings are not needed for internet connections, some providers drop them and save the bandwidth for the real work. This can really upset those that used that.

As to the other issues I can't guess what it is given the clues so far but look at your settings on the modem router and see if the PC you want to reach is in the DMZ entry.

What's the DMZ entry? It's in the router manual and explained online so let's hope that will let it work. There are also issues as folk firewall their machine. This is an area your IT skills matter.

I will check the DMZ setting after I read up on the manual. As far as pin hole goes, in Applications and Gaming I have created the pin hole with the Port Range Forward option.
I just checked the DMZ and that is disabled.

Since port forward requires a lot of knowlege.

I start folk with the DMZ since port forwarding is not something I can support. I know that sounds terrible but it's beyond the scope and level of support I can offer here.

Forget all port forwarding and try the DMZ. It's possible the ISP blocks remote access "for your safety" but with no less then 5 areas that can block this, you get to check all of them.

Thanks for your help Bob.
From your directing me to hunt and research on DMZ, I found the manual online and a set up wizard and started over from scratch on setting up the router. I somehow (not really sure how) have a new IP Address and have the router re-set up so now PCAnywhere works. As far as the ping goes, I have no idea (haven't asked anyone to ping it yet).

Glad to read that I may have helped. As you learn more you can go back to port forwarding but as you see it's not very supportable in a forum. Yes we can discuss port forwarding but as many can't find out which ports to open and some routers just fail on forwards the DMZ steps in to make it work without all the fuss.

And as the learning continues you can move to port forwarding and again, if it fails, use the DMZ.
