Anyone know why this might be >happening? enable ip forwarding in /etc/sysctl.conf. u need to set this line: net.ipv4.ip_forward = 1 then do a sysctl -p to reload it. this way, everytime your network service restarts, it ip_forward will always be 1. not sure where it is actually set but whenever the network service is restarted, your /proc/sys/net/ipv4/ip_forward will always be 0. hth. /erik -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
