I have two sites: the datacenter and the HQ Office. All traffic from the HQ office goes to the Datacenter. This includes the internet. There is current two VLAN: VLAN 50 from datacenter going out to the internet and VLAN 120 for communication between the HQ and Datacenter.
I have a need for setting up a separate network at the HQ office that ONLY need internet access. I need this new network to be totally separate from the existing network. I have to use the existing VLAN 120 between HQ and Datacenter, and I was thinking about doing VLAN stacking. I have Netgear GS724TS switches. Is it possible to do VLAN stacking or is there another way that I can set up another network that has no access to the servers at the datacenter and only has access to the internet.
I am using SonicWalll for routing.
