Another chance for me to display my ignorance :-) All that follows is based on SuSE 7.0. I am changing our ip address range from 172.19.50.x (255.255.255.0) to 172.16.y.x (255.255.252.0) - reason - more numbers. However, while moving over I need to let machines on both ranges communicate eg. clients printing to print servers etc. Is this possible? If I set up 2 interfaces on the server (derby) with ifconfig eth0:0 172.19.50.2 netmask 255.255.255.0 ifconfig eth0:1 172.16.0.2 netmask 255.255.252.0 and turn ip forwarding on with yast, should machines on the 2 ip ranges be able to communicate. eg. ping each other I've tried it and they don't. Am I trying something silly and if not what other steps do I need? Dave Williams
