Hello, By default, in most Linux distros, /proc/sys/net/ipv4/ip_forward = 0 when setting it to 1, ip forwading is enabled. See : Documentation/networking/ip-sysctl.txt And the explanation there says: "Forward Packets between interfaces.". My questions are: 1) What can be the usage of setting /proc/sys/net/ipv4/ip_forward to 1? Could there be any usage for setting /proc/sys/net/ipv4/ip_forward to 1 when NOT using iptables (when the iptables service is down). ? 2) Must there be two (or more) NICs in order that there will be any usage for setting /proc/sys/net/ipv4/ip_forward?
