Hi, Why does this give an error, # iptables -A INPUT -p all -s 0/0 -d 192.168.0.10 --dport 21 -j ACCEPT iptables v1.2.7a: Unknown arg `--dport' Try `iptables -h' or 'iptables --help' for more information. and this, # iptables -A INPUT -s 0/0 -d 192.168.0.10 --dport 21 -j ACCEPT iptables v1.2.7a: Unknown arg `--dport' Try `iptables -h' or 'iptables --help' for more information. But this works, # iptables -A INPUT -p tcp -s 0/0 -d 192.168.0.10 --dport 21 -j ACCEPT Why does it not work without -p and even with -p tcp?
