Can try Shorewall and Webmin combination.
http://shorewall.sourceforge.net/ http://www.webmin.com/
Both are fantastic products. However, the Shorewall module for Webmin was not produced by the Shorewall author but by someone else trying to be helpful. It (the shorewall module for webmin) does not fully support recent versions of Shorewall and I do not recommend it.
Use Webmin. Use Shorewall. Just don't try to use Webmin to configure Shorewall. :-)
