The button 6in4 tunnel opens the configuration for a 6in4 tunnel.
Click on Add to create a new tunnel.
You can set the following properties for the tunnel:
- Tunnel name
- Specifies the name of the 6in4 tunnel.
- Interface tag
- The interface tag that you enter here is a value that uniquely identifies the network. All packets received on this network are marked internally with this tag. The interface tag enables the routes which are valid for this network to be separated even without explicit firewall rules.
- Gateway IPv4 address
- The IPv4 address of the remote 6in4 gateway. The tunnel is only established if the gateway can be reached by ping.
- IPv4 routing tag
- Enter the routing tag for setting the route to the relevant remote gateway.
- Remote IPv6 address
- IPv6 address of the remote tunnel endpoint on the intermediate network, for example, 2001:db8::1.
- Local IPv6 address / length
- Local IPv6 address of the device on the intermediate network, for example 2001:db8::2/64.
- Delegated IPv6 prefix
- Prefix that is routed from the remote gateway to the local device and that is to be used in LAN, e.g. 2001:db8:1:1::/64 or 2001:db8:1::/48.
- Firewall active for this tunnel
- If the global IPv6 firewall is enabled, you can enable or disable the firewall for this tunnel interface here. To enable the IPv6 firewall globally, select IPv6 firewall/QoS enabled in the menu .
Important: Disabling the global IPv6 firewall means that the firewall is disabled for all interfaces, even if you enable this option.
