Hi Geronimo,

IP forwarding is not a cluster function.
It's a function of a single server that has connections to 2 seperate subnets.
And yes it will cause no problems as long as you're not using the server as a crude router.
You use ndd to disable - just set
ip_forwarding=0 in
/etc/rc.config.d/nddconf

HTH,
Jeff

Hi,

Use ndd command to disblae ip forwarding.

check /etc/rc.config.d/nddconf

Also you may need to reboot once

Hi,

#ndd -get /dev/ip ip_forwarding

---> to get the current value

#ndd -set /dev/ip ip_forwarding

---> to set the value

this is a real time parameter in 11.11

With Regards,

Siva.
