The Unauthorized Ubiquiti Routing & Switching course

Connect the router to the internet and share it with inside users while exploring the OSI model, encapsulation, and related protocols through theory and hands-on labs.

Explore the osi model and its seven layers, from physical to application, and learn how encapsulation and decapsulation govern data units from bits to pdu.

Connect the edge router to the internet by linking the ISP router to internet one and ensure internet one is client enabled to receive an ip, subnet, gateway, and dns.

Learn to share internet access by assigning IP addresses, distributing them via a server, and configuring switch ports for network translation, with theory on IP, collision and broadcast domains.

Learn how the tcp/ip model maps OSI layers into four ip layers, and how collision domains and broadcast domains are shaped by hubs, switches, and routers.

Configure the ubiquiti edgerouter x to share internet with LAN devices by creating a switchboard from ports 2-4, enabling DHCP, DNS forwarder, and NAT masquerade for internet access.

Explore routing on a Ubiquiti EdgeRouter, covering static routing and dynamic routing with SBF, plus the theoretical basics of unicast, multicast, and broadcast and related resolution protocols.

Explore arp as the address resolution protocol that maps ip to mac addresses, and distinguish unicast, broadcast, and multicast traffic with arp requests and replies.

Configure static routes and a default route on two Ubiquiti EdgeRouters to enable connectivity between networks, test with pings, and compare static versus default routing.

Explore how OSPF, an interior gateway protocol, uses area zero as the backbone area and the Dijkstra algorithm to automatically advertise connected networks and replace static routes.

Explore how to configure the firewall on the Ubiquiti EdgeRouter, learn about IP addresses and the differences between public and private addresses, and protect your network traffic.

Define IPv4 addressing, distinguish public vs private ranges, explain class A–D, loopback 127.0.0.1, and subnet masks with slash notation, plus NAT concepts.

Configure the edge router firewall to block local traffic by applying a local firewall rule that drops traffic to port 22, then verify connectivity from the LAN.

Master EdgeRouter firewall concepts by distinguishing in and out directions, applying blocking rules near the LAN, and using port 8291 to secure Winbox traffic on a Ubiquiti router.

Explore the virtual private network (vpn) basics, including what ip is, and practice decimal-to-binary conversions, preparing you for more advanced topics like VLSI later in the course.

Apply decimal to binary and binary to decimal conversion to understand ip addresses and subnetwork id, using base-2 arithmetic and powers of two, with examples such as 172 and 192.168.0.0.

Master subnetting calculation to divide a /24 into two subnets with 128 hosts each, assign separate networks for departments, and determine network, broadcast, and usable IPs.

Learn to calculate a summary address by comparing two networks, identifying changing bits, and deriving a single prefix such as 172.16.0.0/22 with a 255.255.252.0 subnet mask to enable aggregation.

Explain how a VPN creates a secure tunnel over the internet, encrypts data, and connects headquarter and branch offices, with remote work scenarios.
