HP box acting as router

[Fabio Yamaia]

Hey there,

I have an HP box running 11.00, and it has 2 network cards conected to 2 different LANs (production and backup LANs).

Right now, this box is acting as a router, passing traffic from one LAN to the other, and I DON'T want that.

Is there a way to prevent this? On SUN's, I know you just have to touch a file on /etc, but what about HP?

Any help is much appreciated.

Hi Fibo ,

What is the default gateway , can you print netstat -nr and post it so that the correct route can be determined.

You need to issue a ndd -set ip_forwarding 0 command. Man ndd for details. This will do it.

Manoj,

Thanks for your help, but I guess that Clay's approach was more correct. Routing table would only affect the local box, right?


Clay,

I guess that's what I was looking for... Another question: if I reboot the box, will I have to set the value again, or once it is set, it stays?

Thank you very much for all your help.

Hi Fabio:

You should set your tuned parameters in /etc/rc.config.d/nddconf . In this fashion, they will be set/preserved atomatically each time the system boots.

Hi Fabio,

No the ndd set is not permanent but you can easily add it to one of the existing rc scripts or create a new one. If you are not familiar with this process then let us know.

Clay,

I was thinking that also, I mean, having to create an rc script, but James' solution seems nicer (and more logical). Anyway, thank you very much for your help.


James,

Thanks a lot for the help. That combined with Clay's first solution was exactly what I was looking for!
