LogMeIn Hamachi, Zero-Config Free VPN Application...

just saw this application while browsing my blog lists and found it via Larkware site. LogMeIn Hamachi lets you build secure VPN network via internet to connect you own computers no matter where they are (NAT to NAT traversal is also ok!). provides simple chatting functions and abilities to create own networks as you want. the free version can create private VPN P2P network with up to 16 nodes in the network to let those computers work just like they are in a LAN environment. you can purchase subscription based services to have more functions.

Hamachi will setup a new NIC interface and create connection to its tunnel servers to making the connections to peers in self-created networks. it claims that after making the connections to peers the rest of the traffic will be pure UDP P2P and will be encrypted.

I just had a test of Hamachi via 3 pc configuration, one is my office pc, the other is my home server and home notebook (behind home ADSL router). the connections via Hamachi VPN network to my home notebook (NAT to NAT traversal) had no problems and the speed is quite cool. the status of connection shows that it is now in p2p mode.

one of the other good thing is that once the installed pc is getting a virtual Hamachi IP, the IP seems not changed while login everytime, thus it's good for setting firewall rules to certain Hamachi IPs to let traffics go through.

the most good thing is, just like what it said, really zero-configuration, just install it, and everything is done, you got a VPN over Internet networking environment!
