[ubuntu] Weird command expansion of iptables command.

ON Ubuntu 14,04 LTS I am attempting to close port 11 to the outside world. I have found a lot of information on doing this but I can't get any of the commands to actually work.

One command line I found was this

iptables -A INPUT -p tcp !-s 192.168.1.0/24 --dport 111 -j DROP; iptables -A INPUT -p tcp -s 127.0.0.1 --dport 111 -j ACCEPT

However when I run the line below in a root bash shell (sudo bash)

iptables -A INPUT -p tcp !-s 192.168.1.0/24 --dport 111 -j DROP

I get this:

iptables -A INPUT -p tcp sudo iptables -A INPUT -p tcp sudo bash 192.168.1.0/24 --dport 111 -j DROP iptables -A INPUT -p tcp -s 127.0.0.1 --dport 111 -j ACCEPT 192.168.1.0/24 --dport 111 -j DROP
Bad argument `sudo'
Try `iptables -h' or 'iptables --help' for more information.

What am I doing wrong.
