I’ve been trying to figure this out myself for the last week, so I thought I would post here while I try and figure this out.
At the moment we have a UniFi access point providing WiFi for the company . We aren’t using VLANs. We have a WAN router and a VDSL router (used by the IT guys). I’ve been asked to implement guest WiFi going through the existing VDSL connection.
My idea was to set up a separate VLAN for guest WiFi (provided by the existing UniFi) that goes through the VDSL connection, unfortunately, the VDSL modem doesn’t support tagged VLANs and we still want to use it for our monster downloads so we it needs to be accessible from the LAN.
Is what I’m trying to do possible, and how do I do it?
Thanks for your help.
If anyone wants to know how I did this:
- Created a VLAN on the managed switch, and choose static tagged for all ports
- On the UniFi, create a guest SSID with tagged VLAN.
3.1 Routerboard, Interfaces, VLAN, create a VLAN on ether2 (which should be a master port)(this is how the routerboard connects to our LAN)
3.2 Routerboard, IP, give the VLAN an IP address, and the WAN port (ether1) a IP address
3.3 Routerboard, IP, DHCP server, delete the existing DHCP server and create a new one on your VLAN port
I think that was all I did.
