Hi, I have a RH 7.3 with 2 ethernet interfaces (eth0,eth1).
I set ip_forwarding to be 1 at /etc/sysctl.conf The problem is that after a short period (20-30 min) , ip_forwarding turned down to 0 again . When I cat /proc/sys/net/ipv4/ip_forwarding I see 0 , and the traffic stops moving from one interface to the other I have also added a static route to one of the interfaces to reach a subnet that is lt gateway interface. That static route is added via " route add -net ...." and not at boot time . When the ip_forwarding is set to 0 , that static route is removed as well. It looks like the ip_forwarding is aged somehow. Any ideas? Thanks, Chava
