NAME

interfaces-forward - forwarding vocabulary for the interfaces(5) file format

DESCRIPTION

Linux allows for configuration of IP packet forwarding behavior on a protocol and interface basis. The following options allow for this configuration.

FORWARDING-RELATED OPTIONS

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.

EXAMPLES

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
