The problem this time is the document I'm using advises to put the following code in the startup script for the interfaces.It's supposed to be for spoofed packekts: For x in lo eth0 eth1 Do Echo 1 > /proc/sys/net/ipv4/${x}/rp_filter Done The only startup script I can find that brings up the interfaces is: /etc/rc.d/rc3.d/S10network Is it safe to add the above code to this file, or is there another script I should be modifiying. And yes I will make a backup of the original first. Thanks. "I Knew I should have taken that left turn at Albuquerque" -Bugs Bunny </BODY> </HTML>
