hey there everybody,
i’ve an issue in a firewall command i hope u help me on.
when i try to type the following firewall command:
iptables -A INPUT -s xxx.xxx.xxx.xxx -dport 8000:9000 -p tcp -j ACCEPT
it gives me:
Bad argument 8000:9000
it complaints about the port range and i cant see in problems in that.
i also tried to change the order of the options but it never worked.
one other thing,
why it don’t allow me to add -sport option in the above command?
thank u very much,

Wildly guessing based on iptables manpage:
Two dashes, not one.
Good luck.
