interfaces-forward - forwarding vocabulary for the interfaces(5) file format
Linux allows for configuration of IP packet forwarding behavior on a protocol and interface basis. The following options allow for this configuration.
The forward executor will only modify the sysctl configuration if these options are provided, otherwise other mechanisms such as /etc/sysctl.conf may be used. forward-ipv4 yes|no Whether the interface should forward unicast IPv4 packets. forward-ipv6 yes|no Whether the interface should forward unicast IPv6 packets. forward-ipv4-mc yes|no Whether the interface should forward multicast IPv4 packets. forward-ipv6-mc yes|no Whether the interface should forward multicast IPv6 packets.
The typical home router scenario will want to forward both IPv4 and IPv6 packets: iface WAN use dhcp forward-ipv4 yes forward-ipv6 yes iface LAN address 192.168.0.1/24 forward-ipv4 yes forward-ipv6 yes
