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! ------------------------ Keith Smith
