IP Forwarding Disabled by Default in Solaris 10 OS
In this Solaris release, IP forwarding is disabled by default. This setting applies to both IPv4 and IPv6 regardless of other system configurations. Systems with multiple IP interfaces that formerly forwarded IP packets by default no longer have this automatic feature. To enable IP forwarding in multihomed systems, administrators must manually perform additional configuration steps.
Workaround: The command routeadm enables IP forwarding. The configuration changes that are the result of routeadm usage persist across system reboots.
-
To enable IPv4 forwarding, type routeadm -e ipv4-forwarding .
-
To enable IPv6 forwarding, type routeadm -e ipv6-forwarding .
-
To apply the enabled IP-forwarding configuration to the currently running system, type routeadm -u.
For more information about IP forwarding, see the routeadm(1M) man page.
