Guarddog – firewall configuration utility

Last Updated on July 11, 2021

Guarddog is a firewall generation/management utility.

Guarddog is aimed at two groups of users, namely novice to intermediate users who are not experts in TCP/IP networking and security, and those users who do not want the hassle of dealing with cryptic shell scripts and ipchains/iptables parameters.

It allows you simply specify which protocols should be allowed and requires no knowledge of port numbers. Generates scripts for ipchains.

Features include:

• Easy to use goal oriented GUI.
• Application protocol based. Unlike other tools, Guarddog does not require you to understand the ins and outs of IP packets and ports. This also reduces the chances of configuration mistakes being made which are a prime source of security holes.
• Lets you maintain and modify the firewall in place.
• Hosts/networks can be divided into Zones. Different zones can have different security policies for different.
• Supports router configurations.
• Runs on KDE 2 or 3, and Linux 2.2, 2.4 and 2.6 series kernels.
• Supports advanced Linux 2.4+ iptables features such as connection tracking and rate limited logging.
• Firewall scripts can be Imported/Exported for use on machines other than the current one.
• DHCP support.
• Uses a “what is not explicitly allowed, is denied” philosophy. Fail-safe design.
