Managed switch VLAN and BT Business Hub
I'm setting up a set of 3 independent offices in one building. We've just had BT fibre installed and have a BT Business Hub with 4G backup.
I want to separate the offices onto individual VLANs so that each is protected from each other but all can access the internet.
I know I can do this with a gateway router like the TL-ER605 but if I don't use the BT hub I lose 4G backup and also BT's Cloud Voice service.
1) Can I use the BT hub with the managed switch running multiple VLANS?
2) If not, can I put the ER605 between the BT hub and the switch?
Also, I'd want DHCP to dole out addresses on each VLAN, but does that mean I need a DHCP server for each VLAN?
Help!
Thanks
