Today I updated several servers running CentOS 4.3, and got the new 2.6.9-42 kernel. One of the machines serves as our firewall. After rebooting I lost all forwarding thru the machine. I reverted back to the 2.6.9-34 kernel and connectivity returned. During the few minutes that the new kernel was running I checked that the routing table looked OK, and with tcpdump I saw that indeed no traffic was going thru from the externel interface to any of the internal interfaces.
Has anyone seen similar behavior??
The two firewalls I upgraded to 2.6.9-42 have been working just fine.
