I have webmin 1.000 running on Redhat 7.3.
I notice that the rule edit screen doesn't seem to let you
set multiple state matches as allowed by iptables:
-m state --state RELATED,ESTABLISHED
I would have to add two rules one for RELATED and
one for ESTABLISHED using webmin.
Webmin doesn't mind the multiple state matches being
already loaded into iptables - you just cant edit them
or add them like that.
Another thing I notice is that webmin doesn't seem to
let you set the "unclean" experimental iptables option.
PS. Webmin is a great tool BTW. Thanks!
