Thanks for the additional information, and posting up the config.  A couple things I notice from the config: - I do not see anything configured on Switch 4 Port 24, which is where the Zyxell router is plugged into. If that port is not configured correctly it may not be able to see the communication on the VLAN. A config like this should work on Switch 4 Port 24 .  # interface ethernet 4/g24 # switchport mode access # switchport acccess VLAN 10 - You may need to setup a static route to point the VLAN traffic out to the router. # ip route 192.168.99.0 255.255.255.0 192.168.99.254 Let me know if any of this helps.
Hi, I am attempting to set up a VLAN for guest wireless traffic to go through our main switches and out to an ADSL router but I am running into some difficulties. We have 3 Unifi AP-AC model access points. Each access point has a physical network connection to 1 out of 4 Dell 6248 switches which are currently in a single managed stack like so. AP 1 -> Switch 1 Port 40 AP 2 -> Switch 2 Port 36 AP 3 -> Switch 3 Port 17 The managed stack and AP's are currently using the 192.168.1.0/24 on VLAN 1 - Default and I have created a VLAN 10 - Guest. The APs have two SSID WLANs, "corporate" which is also on the 192.168.1.0/24 range and a "guest" which is on 192.168.99.0/24. I have set the "guest" to tag its traffic with VLAN 10 and no DHCP is set. I have set the 3 ports above as General Mode, Allowing Any frames and in VLAN - 1 these are untagged and VLAN - 10 they are tagged. I have also set a Zyxell Router with a static address of 192.168.99.254 into Switch 4 Port 24 and set this to Trunk mode for VLAN 10. The router is set to provide DHCP for the 192.168.99.0/24 range. Now when I connect a laptop to our "coporate" WLAN, everything works fine. I receive an DHCP address from our server and I can reach everything as normal. When I connect to the "guest" WLAN, I do not receive a DHCP address. If I set a static address I am unable to ping the router.  Could someone tell me if my setup is correct?
