I'm trying to set up a guest network and am running into problems with the VLANs - I assume.
I have a Unifi UAP with 2 SSIDs (call them internal and Guest).
I have a BT Home Hub v3 serving DHCP on a 192.168.19.*/24 scope - this is the internet network and only generally has 2 leases.
I have a windows server 2012 box serving IPs on 192.168.18.*/24 - this is the internal network used for most things.
I have a web filter that routes between .19.* & .18.* perfectly - essentially a second router.
I have a GS724T switch with 2 vlans set up
VLAN1 in the main, default vlan that is on the 18.* network. All ports apart from 1&2 are assigned to this VLAN.
VLAN2 is the internet vlan and has port 1 (home hub), port 2 (web filter) and port 3 (Unifi AP) I have set the guest network to VLAN2 - but no DHCP gets picked up by the client. I want the guest network to have a 19.* IP - which means no filtering - I have my reasons.
In essence, It appears that DHCP requests aren't being forwarded to the home hub, or the responses aren't being relayed back.
Does anyone have any ideas? This is currently a home project, but it's because we're wanting to do something similar at work.
Many thanks, don't hesitate to ask for any more info.
