Thanks for answering my questions, Peter, and giving me some more to think about. Apologies for all for mnemonic confusion; I meant WLAN rather than WAN, of course. It's the phones and IoT devices on the network that cause me most concern; I'm not so much worried about the state of my Linux boxes.
You can create subnets on the same network. E.g., in our observatory the servers ethernet port has a second address in the 192.168 range, and unknown devices (like phones and tablets from visitors) get an address in that range. Although on the same physical net, that way they lack the rights that other 'official' computers in there do have.
I hadn't even got as far in my thinking as remembering the need for two ethernet ports. How do the pi systems handle that? I had wondered whether a pi would be fast enough. My ADSL line is nowhere near a Gbit; only a few Mbit.
Then a Pi for sure would be enough. You'd need an USB network device as second port (also the 'real' ethernet of the Pi sits on the USB bus IIRC - the reason it doesn't really reach the full speed of a Gbit).
I've got a pi I could experiment with, as well as a couple of old routers that could probably do the job, but the thought of managing another box and keeping it up to date is depressing. Especially when it HAS to work.
Well, OOTB routers are of course fine and convenient. The problem is you tend to forget about them - and also about keeping them up to date :o Security and unattended operation don't go together too well.... -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
