I am having a problem with my mate for setting up Hamachi for VPN. We have both the same version installed and got to the same network but for some reason I can't ping him (Request times out) and he can ping me. He also tried Hamachi with another friend and had better luck since it worked out.
Any ideas on what might be the problem? We both have firewalls turned off. And as a side note, he does have Vista. (with a firewall off I presume)
Check the firewall. Windows Live One Care, among other firewalls, block TCP/IP v4 Ping requests. Look for the ICMP ruleset in your firewall. I have yet to see the OS itself block ping requests, without prior configuration to do so that is. But it is possible.
The router cannot block ping requests from the Hamachi Adapter, as the ping packet is encapsulated. So unless your router can do packet inspection, it won't block you.
