Designing & Implementing Linux Firewalls & QoS using Netfilter, iproute2, NAT, & L7-Filter
Firewalls are used to protect your network from the outside world. Using a Linux firewall, you can do a lot more than just filtering packets. This book shows you how to implement Linux firewalls and Quality of Service using practical examples from very small to very large networks.
After giving us a background of network security, the book moves
on to explain the basic technologies we will work with, namely netfilter, iproute2, NAT and l7-filter. These form the crux of building Linux firewalls and QOS. The later part of the book covers 5 real-world networks for which we design the security policies, build the firewall, setup the script, and verify our installation.
Providing only necessary theoretical background, the book takes a practical approach, presenting case studies and plenty of illustrative examples.
