Protect LAN connection


[link to this post]
 
My ISP is Plusnet, and the router is supplied by them. The wifi does not reach everywhere in the house, so I have set up a TP-link system with several plugs, some of which have wifi and LAN, and some LAN only. This works well.

I have just bought an electric car, and the fast charger is to be installed in a carport at the end of the garden. The supplier has said that it would be beneficial to be able to connect this to the internet, but the wifi signal does not reach the carport, even when using a TP-link plug. I can however, connect a laptop to the internet using a TP-link plug with a LAN cable, so I assure this would also work with the charger. However, this would allow a passer-by to connect their own device to our network via the LAN cable. While this is probably not very likely, it is certainly not desirable.

I would like to know if it is possible to password protect the LAN connection, or protect it in any other way. My understanding of how the network works is quite limited, and I would be grateful for any advice as to how I can deal with this problem.

I'd want to know more about that. I can only think of one benefit from your point of view and that would be to allow you to monitor the car charge state remotely. It would no doubt allow data collection by various companies e.g. a recent report (can't remember offhand where I saw it) about the huge amount of data being fed to numerous companies by a robot vacuum cleaner.

p.s. Perhaps I'm over cautious since my network was hacked some time ago.

This is what their wesbite says:

Why connect to Wi-Fi?

By connecting to Wi-Fi your home charger can offer:

Remote diagnostics, remote support issue resolution.
“Over the Air” software updates.
Energy usage reporting and associated features.
Access to new smart features as they become available in the Pod Point App.

So I can probably manage perfectly well without it, and may avoid yet more surveillance!

I can possibly use my phone hotspot for occasional interactions.

However, I would still like to know if there is a solution, as I am thinking of installing a security camera which I might want to contact via the internet (more external surveillance???)

Thanks for you input

If it is a system that needs constant monitoring over the internet to monitor and resolve problems then perhaps the company would do better to design and build a more robust system?

Definitely. My NVR + 3 cameras and/or a single IP Camera were major suspects. They're no longer connected to my LAN, the NVR creates it's own network.

So what you both saying is that I should not link either my charger or my security camera to the internet. I will have to think about that.

There is an advantage in having the security camera recording being held away from the camera. On the other hand, we don't actually have any major security issues.

But I would still like to know if it is possible to have security protection on the LAN connection. I may find a use for it that doesn't involve Big Brother stealing my life!!

But thanks again for helping.

PS. I can already monitor the charge status of the battery from my phone which means they are already watching me

Definitely. My cameras are connected to the NVR by (hidden) ethernet and that's where recordings are held. The cameras are outside and the NVR is in my 'den'. Burglar Bill would have to break in to the house in the full glare of 8 p.i.r. floodlights with alarms ringing and then search the house to find it 8^)

I need to learn about NVRs then. Perhaps over specified for what I need!

I'm presuming there is power where you want the internet connection (otherwise how will the car be charged)? If the power feed is on the same circuit as your TP-Link devices, could you take a feed from the power supply and put a 13-amp socket and TP-Link Wifi device in a locked cabinet within range of the charging unit?

1. Only necessary when there is an issue
2. And what if an update renders the vehicle inoperative, or worse, working, but unsafe?
3. Not necessary 24/7 : Perhaps helpful to send total data once a year
4. New features...for a battery...

Sorry, but I am completely taken with renewable energy and completely against the marketing of all things nowadays, as it's practically impossible to have any business transaction without the purchaser being asked to submit data on purchase, or during life of product. Everything is a feature, and almost all features are total [censored].

If people stopped giving their data en-mass, companies might get the hint.

There is little need for all that data awareness, unless they're still in a period of testing, which should be clearly stated in the contract as something you HAVE to carry out, or face some form of loss of support. Either way, I wouldn't sign it.

The TP-link device does not transmit wifi (perhaps too far from teh hosue), but does give a LAN signal

A bespoke lockable cabinet containing charging unit plus mains connection and TP-Link with an additional small door over the charging socket (too small to allow any other access to the innards of the cabinet)?

FYI, From the 1st July, an EV charging unit has to be "smart" to be eligible for the government installation grant (which typically pays for the majority of its cost).

This typically means a connection to your home internet.

It is to facilitate the smart grid of the future where rather than firing up an extra power station when there is a spike in demand, non-critical consumption can be briefly turned off instead...

"MAC filter" facility on your router will probably be sufficient unless you have a lot of guests coming and going who want to connect.

Can the charger use a wired ethernet connection or does it only support Wifi?

Can the charger use a fixed IP address? If so you could connect it to a second router next to and downstream of your main router. This second router could have an obscure 10.x.x.x network IP address and DHCP disabled. That would make if difficult for anyone else to use the connection as they would need to know the router's address.
