You did draw a network diagram so I'm guessing you are trying to use the box with the routes above as a gateway. The obvious thing that comes to mind is wether IP forwaridng is enabled. cat /proc/sys/net/ipv4/ip_forward this should return 1 you can set it manuall by doing echo 1 > /proc/sys/net/ipv4/ip_forward Or more permanently using in /etc/sysctl.conf with net.ipv4.ip_forward = 1 Any more help than that requires some ASCII art on your part :) -- John http://www.inodes.org/ -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
