This book is designed to be a friendly step-by-step guide to common networking and security tasks, plus a thorough reference of pfSense's capabilities. The book covers hardware and system planning, installation and upgrades, backups, firewalling fundamentals, port forwarding and Network Address Translation, bridging, Virtual LANs (VLAN), Multi-WAN, Virtual Private Networks (VPN) using IPsec, PPTP, and OpenVPN, traffic shaping, load balancing, wireless networking and captive portal setups, redundant firewalls and High Availability, system monitoring, logging, traffic analysis, sniffing, packet capturing, troubleshooting, and software package and third-party software installations and upgrades.

The most practical, comprehensive solution to defending your network perimeter. Get expert insight from the industry's leading voices: Stephen Northcutt and the expertise of the SANS team. Inside Network Perimeter Security is a practical guide to designing, deploying, and maintaining network defenses. It discusses perimeter components such as firewalls, VPNs, routers, and intrusion detection systems, and explains how to integrate them into a unified whole to meet real-world business requirements. The book consolidates the experience of seventeen information security professionals working together as a team of writers and reviewers. This is an excellent reference for those interested in examining best practices of perimeter defense and in expanding their knowledge of network security. Because the book was developed in close coordination with the SANS Institute, it is also a valuable supplementary resource for those pursuing the GIAC Certified Firewall Analyst (GCFW) certification.

Gigabit VPN router delivers high-speed, secure and reliable network performance for employees at the office or on the road. OpenVPN server support allows clients running on employees' devices to connect using two-factor authentication. WAN failover allows your business to continue its network operation even if one of its WAN connections fails. Dual-WAN load balanced aggregates bandwidths of both WAN connections to achieve a higher Internet bandwidth. Integrated firewall supports URL filtering and access rules that allow an administrator to further regulate the traffic within the business network based on the services (i.e. TCP/UDP ports) and source/destination IP addresses. 802.1Q technology keeps resources in different SSIDs/VLANs separated, while allowing specified traffic to traverse between VLANs with inter-VLAN routing. Intuitive web administrative interface allows small business owners to deploy and manage the routers without professional IT staff onsite.
