That could work for our dedicated employee laptops.
But we have one computer--in the building but outside our network, connecting to the Internet via Meraki wifi--that is dual purpose: used sometimes by employees (who need to be able to RDP to their desktop inside the network) and sometimes by sales reps (who should remain outside our network.)
Since we already have the Meraki VPN, I thought it would be a simple matter for this desktop to connect to the VPN when needed.
But it looks like that isn't possible to do that through the Meraki wifi.
We do have a jack in that room that goes to our network switch. I'll probably leave that computer as is (outside the network) and when employees need to do a demo, I'll loan them a laptop and plug it into the jack for the meeting.
Thank you both for your input.
