Hi, AFAIK, everything you feed to iptables-restore is given as arguments to "/sbin/iptables". Thus, having "echo > 0 /proc/sys/net/ipv4/ip_forward" in the iptables.rules file should leads to the execution of "/sbin/iptables echo > 0 /proc/sys/net/ipv4/ip_forward" which should normally give something like :
# /sbin/iptables echo > 0 /proc/sys/net/ipv4/ip_forward Bad argument `echo' Try `iptables -h' or 'iptables --help' for more information. Thus, I suggest you remove the "echo > 0 /proc/sys/net/ipv4/ip_forward" line from your iptables.rules file and that you put it in a shell script (as opposed to an iptables-restore script). I also suggest you swap the "0" and the ">" sign. Reason is that the effect of your command is to write a new line in file "0" and in file "/proc/sys/net/ipv4/ip_forward", as opposed to the - I suppose - wanted behavior, ie. to write character "0" to file "/proc/sys/net/ipv4/ip_forward".
