Friends, I am using iptables 1.5.7 + linux kernel 2.6.20.2 and the last patch-o-magic. But, when I exec this rule iptables -I INPUT -s 192.168.0.0/24 -p tcp --dport 21 -j ACCEPT This error occurs iptables: No chain/target/match by that name This occurs in the chain ACCEPT, DROP and REJECT, but if I modify the rule for the following one: iptables -I INPUT -s 192.168.0.0/24 -p tcp -j ACCEPT or iptables -I INPUT -s 192.168.0.0/24 -j ACCEPT it is accepted, the error only occurs when I specify the the origin or destination port. Any Ideas to solve this? Thanx. iptables -L output: Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination modules loaded: /sbin/modprobe ipt_REDIRECT /sbin/modprobe ipt_state /sbin/modprobe ipt_recent /sbin/modprobe ipt_MASQUERADE /sbin/modprobe ipt_LOG /sbin/modprobe ip_tables /sbin/modprobe iptable_filter /sbin/modprobe iptable_nat /sbin/modprobe ipt_conntrack /sbin/modprobe ip_conntrack
