Matt,

The kernel parameter ipforwarding specifies whether or not IP packets
are forwarded. The default is no (denoted by the value 0).

To examine the current setting:
# no -o ipforwarding
To enable:
# no -o ipforwarding=1

The change takes effect immediately and is effective until the next time
you re-boot. To make the setting permanent, add the above command to
/etc/rc.net.

This does come with a possible performance impact.

The command to enable IP forwarding is : no -o ipforwading=1
