SOHO Router Lab: DHCP, Reservations and Port Forwarding
Configure a small-office router: a DHCP range, fixed addresses for a printer and a recorder, a port forward and a guest network.
Last updated
SOHO router · Intermediate · About 10 minutes
The scenario
The same dental practice is adding equipment. A network printer and a camera recorder need addresses that never change, the recorder has to be reachable from the owner’s phone when she is out, and patients in the waiting room want Wi-Fi.
The router is already secured. Set up addressing, the port forward and a guest network that can’t see the practice’s own devices.
A simulated router admin page that runs in your browser. Each setting is checked as you change it.
Your tasks
0 of 5 doneLimit the DHCP range to 192.168.1.100 through 192.168.1.200, so the lower addresses are free for fixed devices. (not done yet)
Reserve 192.168.1.20 for the printer. (not done yet)
Reserve 192.168.1.50 for the camera recorder. (not done yet)
Forward external TCP port 8443 to the recorder’s HTTPS port, 443. (not done yet)
Turn on a guest network named BrightSmile-Guest, with its own passphrase and client isolation. (not done yet)

Guide
How to get the most from a lab
Type the commands yourself
Typing a command, getting it wrong and fixing it is what makes it stick. Use the hints when you’re stuck, not before.
Check the walkthrough afterwards
Every lab has a worked solution with the reason for each step. Read it even when you finished: there is often a shorter way.
Do it again from memory
Reset the lab a day later and do it without hints. If you can, you know it. If you can’t, you’ve found what to study.

Is this a real router’s admin page?
No. It’s a simulated admin page with the settings that small-office routers share. Names and layout differ from one make to another, but the settings, and the reasons for each one, are the same.
Which exams does this lab help with?
It practices skills from CompTIA A+ Core 1 (Networking), CompTIA Network+ (Network Implementation) and CompTIA A+ Core 2 (Security).
Do I need an account?
No. The labs run in your browser and nothing is saved. Sign up only if you want OpenpassAI’s full labs and progress tracking.
