Hamachi

Any users of the above? Just wanted to check how it worked with the IP addresses. Does each user in your network get a virtual IP provided by the Hamachi server on login? Does it only work from machine to machine too or can I link my network up to the VPN it creates?

Alternatively can anyone suggest software to use with a popular VDSL router that has a VPN bridge so single users could log to my router (on Infinity so I can handle a few 4-10Mb connections through my router if I must).

OpenVPN. Can do everything you are asking for.. I aint used Hamachi in years, just EoIP with openVPN tunnels.

1 IP per Hamachi client.

Machine to machine.

Sorry to bring up an old thread but i have just installed hamachi and i must say it seems pretty cool what you can do with it but im just curious to know why you dont actually have to set anything up router side for this to work? What port does it come through on my router any ideas?

Hamachi uses several ports to achieve connectivity to the mediation servers, and to peers.
Server Connectivity

* TCP 12975 (initiator port)
* TCP 32976 (session port)

If the above ports cannot be used to achieve a connection, Hamachi will try again using SSL (TCP 443).
Peer Connectivity

Peer connectivity has several methods and ports. By default, Hamachi will broker a peer connection over UDP. UDP uses random ports by specification, so it is not possible to open a single port for peer connections for UDP.

If UDP direct connectivity cannot be established, Hamachi will try to initiate a relayed UDP connection. This is done with the target of:

* UDP 17771 (relay connection port)

I guess you don't need to set any thing us as it might use UPNP.

Thanks so much for that Steven much appreciated. To be honest i though all the port on my 7800n router would be closed by default apart from the obvious ones like 443 etc how wrong i was

Doesn't it work because its all based on outgoing connections which aren't usually blocked by a router? Basically the same as LogMeIn where the machine is available because it has connected out to a central server.

Indeed. No need to open ports or rely on upnp.

Hamachi uses a server-assisted NAT traversal technique, similar to UDP hole punching. Detailed information on how it works has not been made public. This process does not work on certain combinations of NAT devices, requiring the user to explicitly set up a port forward. Additionally 1.0 series of client software are capable of relaying traffic through vendor-maintained 'relay servers'.
