Your problem is in the routing table on the firewall box. See below for details.

The host has no default route, you will note, and network 65.167.30.96/27 only covers the address range .96 to .127 . QED. The easy quick fix is to change the netmask on the eth0 IP address from /27 to /24. If that works -- by which I mean that the default route is now installed and you can ping both the gateway and beyond it -- then all that is left is for you to discuss with your ISP what address/netmask you should be using (something no one here can guess; all we can do is note that some combinations, such as the one you are trying to use, will not work). If this does not fix it, then send an updated trouble report. (Once I saw the routing-table problem, I did not examine the firewall ruleset you posted, so I don't know if it too has problems.) -- -------------------------------------------"Never tell me the odds!"-------- Ray Olszewski -- Han Solo Palo Alto, California, USA [EMAIL PROTECTED] ------------------------------------------------------------------------------- ------------------------------------------------------- This SF.NET email is sponsored by: AMD - Your access to the experts on Hammer Technology!
