interfaces-forward(5)
# 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
```
