Configure a PC for internet only access

[Tinribs]

Hi

Our A Level ICT teacher has setup a Linux sandbox environment. We need to set things up so that Linux box can access the internet via our existing infrastructure but that cannot see or be seen by (at all) the rest of the school network. The computer should only be able to access the internet but it should still go out through our cloud hosted NetSweeper firewall.

It will be connected wired to an Aruba switch. We have VLANs setup on the switches and we even have an internet only VLAN that is setup for our guest WiFi users. Our Wifi is down at the moment (another story). I tried connecting the computer using the Guest Only VLAN but it doesn't get connected (to the internet).

I'm a bit of a noob when it comes to this so I'm guessing now but is this down to the IP address/setup on the Linux box (ie do we just need to assign it a static IP on the guest VLAN)? Failing that would I need to look at ACLs on the Aruba switch? I would have no idea how to go about that. Would the DNS settings on the Linux box still need to see the school network's DNS servers?

 

I'm guessing this is pretty straightforward but it's a new area for me - ish. I have configured switches and set ports to VLANs etc so I have a basic idea of the HP CLI commands - just never got into ACLs

TIA
