When listing try iptables -L -n

also you should see a port, ex:

ACCEPT     tcp  --  10.0.0.0/8           0.0.0.0/0           state NEW tcp dpt:22 

or in your case I'm guessing ici is the protocol and you grep ici from /etc/services you'll see port 2200

I would just use the IP on the rule unless you have a reason not to.

Hi,

I added a rule : iptables -A INPUT -p tcp -s 24.221.202.36 --dport 22 -j ACCEPT

and when I list the iptables I see: 

ACCEPT     tcp  --  24-221-202-36.pools.static.spcsdns.net  anywhere            tcp dpt:ici

Are the below two rules the same?

iptables -A INPUT -p tcp -s 24.221.202.36 --dport 22 -j ACCEPT
iptables -A INPUT -p tcp -s 24-221-202-36.pools.static.spcsdns.net --dport 22 -j ACCEPT

in other words can I use 24-221-202-36.pools.static.spcsdns.net in place of the IP?

Also I do not see the port when I issue iptables -L ?  How can I sell if the rule applies to a specific port?

Thanks!
