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?

With warm regards,
-Payal
