iptbales problem

[alesko]

Hello guys,   I'm tryin' to do some ip-forwarding but without success.IPTABLES won't accept my parameters.   I want the linux-box to forward all packets which come from my internal network.         bash# iptables -A FORWARD -s 10.0.0/24 -d 0/0 -j MASQUERADE   returns:   iptables: invalid argument
