Protecting and controlling Virtual LANs by Linux router-firewall

This research presents analysis of UNIX/Linux open source solutions for routing and filtering regular and VLAN network traffic. Also, it includes developing new software and combining it with existing solutions for network protection. Developed firewall is functional in real environment, which includes: support for stateful inspection, support for routing between different VLANs, additional features (web administration interface, address translation, proxy arp, log records, intruder protection). Also, it is fully adjustable compared to existing solutions which are not fully adjustable mainly because of code protections.
