Can't ping each other

[MIXEDD]

Hello good people. I have installed Hamachi/TeamViewer and I have created a VPN. Everything is done correctly as far as I know. With these 2 programs I have the same issue. When my friend connects to me or I connect to him. I can ping him. But he can't. I don't know what's the cause of this issue because all other my friends can connect to me successfully and ping me also. Any help would be appreciated. Thank you!

So
a) you can ping anyone
b) everyone EXCEPT joeUser can ping you

that means joeUser's machine has a firewall (or vpn) setting restricting the operation

He dones't have a VPN and I turn off his firewall completely and that won't fix the problem. He's internet is working without a router. Maybe that haves to do something with this?

Perhaps the router is blocking ping to prevent a DoS attack?

 

[DelJo63]

yes, that is a common feature that causes problems

If so. How do I manually do it? I'm not really in to all this stuff.

use the browser to access the router config - - you need the password.

each manufacturer has a setting (usually associated with the WAN side) to
enable / disable ping from the Internet. That is done for security reasons.

Which raises the question, WHY do you need ping? My router has ping disable and
the Internet & I have been happily married (ie working) for years.

I would guess you REALLY need something more like

and to test that the program/port required on both ends are running and not blocked.
(ps: just because you shutdown the firewall does not assure you unfettered access).
