Technical access details
What you connect to
A dedicated lab web portal, accessed securely over HTTPS. No VPN is required for browser-based console access.
Session security
Your credentials expire the moment your session ends. The lab is wiped and reset before the next user connects.
Optional: packet capture
Install the Cloudflare WARP client (Zero Trust) to route your session locally and capture live traffic with Wireshark.
Session extension
If the next session is free, extend by 6 hours with one click directly from the lab portal, charged at the standard rate.
Browser compatibility
Use Chrome, Firefox, or Safari. If Brave blocks a topology interaction, disable Shields for the lab URL or switch browsers.
