# 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
|
|
```
