Thanks for the link it's great. but how do I do the following ? Allow from: all the way up to ?? – compcobalt Nov 11 '13 at 16:21
@compcobalt have you looked at the rules in my answer? --src-range X-Y should work for any arbitrary range of addresses. – plasmid87 Nov 11 '13 at 16:23
@plasmid87 that would be super cool and easy to do if I had access to a config file for the firewall :( – compcobalt Nov 11 '13 at 16:25
@compcobalt If you don't have "access to a config file for the firewall" how do you expect to make ANY changes? Come now my good man, be reasonable! We're sysadmins, not magicians! – voretaq7 Nov 11 '13 at 17:54

Try the iprange module. e.g.,:

iptables -A INPUT -p tcp -m iprange --src-range -j ACCEPT
iptables -A INPUT -p tcp -m iprange --src-range -j ACCEPT


As this must be done through the Webmin interface, try Confirm here with "Mask Bits" set to 19.

I'm using Webmin to insert the ip addresses, I cannot add this anywhere ? – compcobalt Nov 11 '13 at 16:22
@compcobalt if webmin doesn't provide direct iptables editing, I suggest following their instructions for configuring the firewall and use the commands listed in my answer. – plasmid87 Nov 11 '13 at 16:27
@compcobalt I've updated my answer to reflect the constraint of doing this via Webmin. – plasmid87 Nov 11 '13 at 16:37
