-Tinc is a newer VPN technology that allows you to create partial/full mesh VPN connections without having to define every endpoint, as you'd have to with other VPN protocols.

+Tinc is a newer VPN technology. Unlike with other protocols, it lets you create partial/full mesh VPN connections without having to define every endpoint. A minimum of configuration is needed for each site. It's the quickest way to develop a mesh VPN between network sites.
 The Tinc Daemon menu is divided into tabbed sections, including Tinc Configuration, and (VPN) Hosts.

-**Interface type:** TUN/TAP: Here, you specify the communication protocol used within your VPN. TUN is routed, and runs at the network (IP) layer. TAP is switched, and runs at the datalink layer. Generally, you should choose TUN. For more information on these protocols, see the "Interface Type" section of the [[:vpn-server|OpenVPN Server]] wiki page.

 ===== Hosts Tab =====
-Most of the hosts on your network should be defined on this page. Tinc doesn't need all the hosts to be defined. It's able to use a relay to reach secondary hosts if the end devices are not able to communicate. This can be happen for various reasons, such as the presene of NAT devices between hosts. However, you do need to define "yourself" on each Tinc device.
+Most hosts on your network should be defined on this page. Tinc doesn't need all hosts to be defined. It can use a relay to reach secondary hosts if the end devices can't (yet) communicate. There are various reasons hosts may not be able to communicate. This includes the presence of NAT devices between them.
-**ConnectTo:** This flag and can be set to "On" or left blank. This tells the local Tinc daemon whether it should attempt a direct connection with another host (not including a relayed connection to another host).
+However, you do need to define "yourself" on each Tinc device.
-**Name:** As on the Config tab, this is the unique Tinc identifier defined in the Host Name field.
+ \\
-**Address: **This is used only when direct communication is possible and defines the IP address or FQDN (fully qualified domain name) where the host can be found. Direct communication means without relay.
+{{:pasted:20230111-110422.png?800}}
-**Port: **An empty value configures the default setting (both TCP/UDP on port 655). You might need to tweak this value for devices on the network that do not have root/administrator privileges (not applicable to tomato).
+ \\
-**Compression:** In some cases, compression may increase VPN speeds. Here, the default of "0" (disabled) can be tweaked to as high as "11". All the nodes must be configured with the same compresssion settting. Since most VPN traffic is already compressed/encrypted at the application layer, think carefully about whether you really need this enabled. Enabling compression will add extra workload to the CPU, and may not increase speed/throughput.
+**ConnectTo:** this can be set "On" or left blank. It tells Tinc to connect directly to another host (without a relay).
+ \\
-**Subnet:** Defines the primary subnet reachable via the host being defined.
+**Name:** as on the Config tab, this is a unique Tinc identifier defined in the Host Name field.

-**Ed25519 Public Key:** This is where you enter your Ed25519 encryption Public Key.
+**Port: **if blank, sets the default setting of TCP/UDP(655).
-**RSA Public Key *:** If you are using an RSA key, you must define the public key on for each host here. RSA is optional in Tinc 1.0+ .
+You might need to tune this for network devices without root/Administrator privileges (but not FreshTomato).
-You must provide the minimum information for every host you define before you can click OK and proceed to the next row. Clicking OK does not save the settings. After you've defined all hosts, and clicked "OK" for each, you must then click the "Save" button at the bottom. Only then will all your host settings be saved.
+ \\
-**Custom:** In this field, you are free to define custom configuration settings for each host. For example, if a host is communicating with a second subnet, you could add something like: //Subnet = 10.10.8.0/24// . Please ensure this is consistent with the host IP/subnet + config-page "netmask" setting.
+**Compression:** lets you set the compression level (between the default of "0" (disabled) and "11").
+Sometimes, compression can increase VPN speeds. You must configure all nodes with the same setting. Think carefully about whether you need this, as most VPN traffic is already compressed at the application layer. Enabling compression adds extra CPU workload and may not increase throughput.

+**RSA Public Key: * ** if you're using RSA encryption, you must define each host's public key here.
+RSA is optional in Tinc 1.0 and later. You must provide minimal details for all hosts defined before you can click OK and go to the next row. Clicking OK **does not** save settings. Only after you've defined all hosts, clicked "OK" for each, and clicked "Save" will all host settings be saved.
