In Soloaris 10 routeadm command and the ifconfig command can be used instead of the ndd command to set IP forwarding. The main advantages are
- The settings are persistent across reboots.
- The new ifconfig router and – router commands can be placed in the /etc/hostname.interfaces files, along with other ifconfig commands that are run when the interface is initially configured.
To enable
# routeadm -e ipv4-forwarding
# routeadm -e ipv6-forwarding
To disable
# routeadm -d ipv4-forwarding
# routeadm -d ipv6-forwarding
In the previous Solaris releases
To enable
# ndd -set /dev/ip ip_forwarding 1
# ndd -set /dev/ip ip6_forwarding 1
To disable
# ndd -set /dev/ip ip_forwarding 0
# ndd -set /dev/ip ip6_forwarding 0
If you want to enable IP forwarding on a specific IPv4 interface or IPv6 interface.
# ifconfig bge0 router
# ifconfig bge0 inet6 router
To disable
# ifconfig bge0 -router
# ifconfig bge0 inet6 -router
To precede any routeadm settings to take effect on the running system, use the following command:
# routeadm -u
