http://www.linuxquestions.org/linux/blog/unSpawn/2006-02-02/Constructing_ZoneAlarm_for_Linux is the reply to the question you seem to be asking.
I?ve been using Guarddog to configure iptables. I know with ZoneAlarm on Windows you can not only control what ports are open, but what specific applications are allowed to connect to the Internet. Is it possible to do the same with Guarddog (or any other iptables front end)?
Thanks in advance.
Yes, it is possible to do that with Guarddog via creating a new zone with the IP you want to allow/disallow and linking it to the local zone. From there you can decide what connections you want to allow/block for incoming and outgoing between your computer (the local zone) and the IP/IP range (your new custom zone).
This following link explains how to create zones in Guarddog: http://www.simonzone.com/software/guarddog/manual2/using-guarddog.html And this one explains how to edit the zone's properties under the protocol tab:
It's actually exactly like every other firewall in concept, but organizes it in a much different way. Instead of individually allowing incoming and outgoing ports for a specific IP/IP range, i.e. "zone", it allows you to configure the allowed incoming and outgoing ports for a zone all in one whack.
Another front end by the name of Firestarter has the kind of interface you're probably more familiar with. Here are some screenshots:
