i have made our host disable his firewall and enable NAT i have constructed the ip adress like you said with ("his ip":26656)
and still error
Try to open cmd and ping your friend ip (ping <ipaddress> without port so like, ping 25.58.150.18 ). Goes correctly?
what is the cmd?
also the ping idea does not work
Open the Start Menu and type cmd. If ping don't work you have fix somehow hamachi.
