Gs728TP VLAN Isolating a single port with only internet
Boot version: 2.0.0.11 Software version: 6.0.1.14 Port 9 Needs to be isolated from the network but also receive internet from port 24. Ports 1-8,10-23 also need to receive internet from port 24...

So create a new VLAN, remove port 9 from any other VLAN, put port 9 [U]ntagged including the same PVID, and make that new VLAN [T]agged on the uplink/router port. Ensure the sub-interface is also operating as tagged for that very same VLAN on the security appliance.

The plan is when I actually have a way to plug this stuff into the switch configurations to split the networks, I am going to configure another sub-interface on the SonicWall Firewall that is plugged into the port 24. I will provide adressing and DHCP to port 9 and forward it to the main IP just like all other traffic is done on what will be the main VLAN. I just want to make sure on its way back and out it stays on its own port.

So these would be the only Switch side changes I need to make?
And then just make sure the SonicWall is prepped to expect tagged traffic on VLAN 13, and then provide a DHCP scope for that sub interface, and make the traffic shoot out to the ISP provided IP? Sounds good to me after I get this set up will report back here, soonest being after hours tommorow.
