How come I can't ping people but people can ping me?

[jainf]

I search the forums and I can't find a solution for me yet. I run on windows 7 64 bit, I use microsoft security essentials for AV and I use default windows firewall. 

I can't ping other people even though we have a direct tunnel, but other peopel can ping me. This problem only applies to my computer, even though my sister uses the same modem she does not have this problem.

Any suggestions?

pings are most often accepted or rejected by the firewall

if you set your hamachi network type or location to "Home" the Windows 7 automatically setup the firewall to let the operating system respond to pings on that network interface.

see here for more info

read to the bottom of that post for W7 info and another link to a MS page

Having Hamachi as a Home network type on your computer lets others ping you.

As you stated, the problem is that you cannot ping others.

The solution might be to ask others to set the Hamachi network to the Home type.

i have this same problem and yet it still will not work even after my friends changed theirs to a home network

I've seen where other people suggest changing router settings that deal with blocking pings from WAN (Wide Area Network, i.e. the internet). But I would not think that such settings would matter to Hamachi connections. My guess is that the computers that cannot be pinged have their firewall setup to block pings. This firewall could be one built into the operation system (OS) or one that is a part of a security suite.

For the Windows Vista OS and above, it is possible to set the Hamachi network connection to the Home network type and still have the OS firewall block pings. Here is a link to some info on Vista's settings:

Windows 7 is about the same.
