Explore pfSense interface types, including LAN, external, optional, VLAN, IPsec, VPN, VIPs, management, bridge, and LCP, with practical steps to assign, tag, and configure for reliable network segmentation.

Configure pfSense to add vlan 100 on the LAN interface, assign it, enable the dhcp server, and set 192.168.10.254/24; verify connectivity through a switch trunk and diagnostic ping.

Configure a lcp interface between pfSense and a Juniper mx router by enabling lcp, assigning 10.10.1.1/24 on pfSense, and testing connectivity with a ping.

Configure a pfSense bridge interface to connect two sites via a private leased line. Set up bridge LAN 192.168.11.254/24 with DHCP 100-200 and disable hardware checksum offload for the VM.

Learn to configure static routes on pfSense across two sites by creating gateways on the log zero interface, adding routes to reach the management machines, and validating connectivity.

Master pfSense firewall rules to control traffic with actions like pass, block, and reject, using interfaces as security zones and prioritizing critical services through stateful, best-practice configurations.

Explore virtual IPs to enable redundancy and failover, load balancing, and IP aliasing on pfSense interfaces using CARP, IP alias, and proxy ARP for multi-band setups.

Learn the essentials of nat, including source, destination, and static nat, to connect private networks to the internet and support port forwarding with pfSense.

Explains source NAT and outbound NAT on pfSense, comparing automatic, manual, and hybrid configurations, and shows how private IPs translate to a public WAN IP for internet access.

pfSense uses destination NAT to forward external requests from a public IP to an internal server, translating the destination and port, with responses returned via source NAT.

Implement static NAT in pfSense to map a public IP to an internal IP with all ports, enabling bidirectional traffic for hosting, remote access, or VPN servers.

Explore three popular vpn options—IPsec, OpenVPN, and WireGuard—and learn how they secure connections, handle encryption, authentication, and routing for enterprise and remote setups.

Create a three-site pfSense topology with an internet gateway, cloud appliance, and wan and lan interfaces; assign private IPv4 addresses via DHCP and configure DNS and gateways to reach 8.8.8.8.

Compare IPsec, OpenVPN, and WireGuard to help choose pfSense, highlighting WireGuard’s high performance, simple configuration, modern cryptography, and low overhead.

Explore IPsec, a secure virtual private network protocol that encrypts and authenticates data, creates IPsec tunnels, and supports site-to-site and remote access connections between geolocated networks.

Configure a policy based IPsec VPN between sites using pfSense, with IKEv2 phase one, phase two negotiations, and encryption domains to control intersite traffic.

Configure a route-based IPsec vpn using a virtual tunnel interface and routing tables rather than policies. Add static routes to direct traffic and support dynamic routing.

Install and manage OpenVPN and WireGuard packages on pfSense across sites, configure remote access and site-to-site connections, export OpenVPN client configurations, and verify DNS and policies.

Explore how OpenVPN in pfSense provides flexible, route-based remote access with UDP or TCP transport, strong encryption, and versatile authentication, plus steps to configure and test a remote access VPN.

Master dual WAN configuration in pfSense, enabling active backup and load balancing through gateway groups and policy routing, with hands-on topology and failover tuning.

Traffic limiters restrict bandwidth for specific traffic to ensure fair distribution and prevent congestion, using tail drop, codel, red, read, pi, and generalized red with schedulers like vfq and qfq.

Configure pfSense traffic limiters and a traffic shaper to restrict download to 50 Mbps and upload to 30 Mbps, applying rules on the LAN interface.

Master traffic shaping in pfSense, prioritizing VoIP, video, and gaming while allocating bandwidth; compare priority, class-based, and HFSC queuing, plus limiters for control.
