Peer Specific Settings

This menu will show your local Hamachi IP and nickname. You will see settings for:

Tunneling Domain
Used for Layer 3 tunneling domains. HIGHLY advanced and prototype functionality intended for advanced usage of the tunneling system. Starting with version 1.0.2.0, Hamachi can manage multiple virtual adapters. Each adapter is associated with its own tunneling domain or TD, which is a fully isolated tunneling environment. You can assign a TD for each peer, and this ensures that all peer's traffic passes only through the virtual adapter of its TD. The adapter can then be custom configured (including IP addressing, firewalling and Hamachi:Windows File Sharing settings) to properly match the security, trust and topology of domain's peer group.

Peer VPN Address
Hamachi now supports changing the IP of the Hamachi adapter to a non-Hamachi IP, ex. 172.16.0.1. This setting is used when the peer has changed their IP, and you'd put that IP here. Unless you have a specific need to completely change the IP scheme of your Hamachi VPN, it's recommended that you use Peer VPN alias instead, as it does not require every peer to manually configure the IP settings of their Hamachi adapter manually.

Peer VPN alias
This feature replaces Hamachi:aliases.txt in Hamachi. This feature is used to bypass "Class C" limitations and essentially do an IP mask of the IP so that any application will be able to access an IP in the Hamachi range as being in the same subnet.

Example: 3 IP's, 5.10.20.30, 5.20.30.40, and 5.30.40.50 can be aliased as 5.10.10.1, 5.10.10.2, and 5.10.10.3 if the local computer had the Hamachi address of 5.10.10.5 and any game/application would see them as their alias accordingly.

Local Forwarding
This setting controls if Hamachi allows hosts from its local network to send/receive traffic to/from the peer. When the setting is set to disabled, only packets from local 5.x.x.x IP are sent over the tunnel and only packets destined for local 5.x.x.x IP are accepted from the tunnel.

Remote Forwarding
Similar to local forwarding, this setting controls if Hamachi allows hosts on peer's physical network to send/receive traffic over the tunnel. When the setting is set to disabled, only packets from peer's 5.x.x.x IP are accepted from the tunnel and only packets to peer's 5.x.x.x IP are sent over the tunnel.

It might be helpful to think of forwarding settings as gates guarding an access to the physical network the respective computer is a part of. If the forwarding is disabled, computer's immediate physical network is not accessible from the other side of the tunnel. Note, however, that enabling the forwarding does not enable Windows IP Forwarding. See Routed Tunneling for details.

Encryption
Used to configure per-peer encryption. In order for the encryption to be actually turned off, both sides need to have it set to off. Otherwise the encryption will remain enabled. You can only disable encryption between two Premium machines, otherwise this setting is ignored.

Compression
Used to configure per-peer compressions settings. Similar to encryption setting, the compression is enabled only if both ends of the tunnel turn in on. You can only turn on compression between two Premium machines, otherwise this setting is ignored.
