I have an Airbnb guest suite that uses the same router that I use. I give them a separate WIFI network connection that is supposed to be safe (from them hacking into my network that I use). However, I also provide for guests a wired connection. I was wondering that is a safe thing to do.

I will let you decided whether or not it is safe with a true story. A few years ago, in my town, a former police officer had his home raided by state, federal and local police because of child porn. After a four hour search of his home and computers, he was cleared. It turned out he was sharing his internet with a neighbor who was doing the crime. It ended with it being suicide by cop.

IMO, most people have smartphones these days, If you provide cable tv, then they should be good with just their phones for internet access.

As a general rule, the greater access you give, the greater the attack surface, so minimising the access minimises the risk.

Personally I would never "rent out" my house to strangers, to me it's nothing but a recipe for trouble. If you're allowing strangers into your home, then there are no safe options really, so worrying about whether a wired connection is safe or not is IMO immaterial.

However, each to their own, and the world would be a much less interesting place if we were all alike.

I don't share any interior space with guests. They can't physically access the router or modem either.
My question is whether guests can hack into my computer if they're using a different WIRED channel on the router than the wired channel I use, the same way that someone can hack into my computer if they used the same WIFI network as i use. This is kind of a follow up to this thread. Vulnerabilities if someone has your WIFI password?

I'd still be careful if you allowed Network Sharing for your family use.

 

[Gary R]

So as I understand things, your guests have an ethernet socket in their accomodation, which connects through to a port on the router, and is configured to use a network that is separate from your own family's network.

If that is the case, then the only way they could access your family's network is if they could re-configure the router, and provided they do not have the router's Username and Password, that's going to be problematic.

So in essence, what I'm saying is, if things are as I've stated, then a hard wired connection to the router should be no more insecure than a wireless one, or if it is, then I'm not aware of how it could be.

So many things cross my mind, but the first thing I'd be wondering is if that computer was ever on the home network. If so, I believe switching to Wi_Fi (yea, I brought a usb network adapter with me) would get me in.

I'd turn home networking off on all my networked machines and don't use the Sharing Wizard.

I also would and not share any folders on any of my computers hard drives. Doing this would require your user name and password for wired access to your computers and only if they had shared folders. If you need to share a folder later you can share it to transfer the files you need then unshare it when done.

As far as wired and WiFI access to the guest locations get another wireless router specifically for guests then, then run one wired cable to it from your router, to the new routers wan port, assign it a differnet network IP address than your network, then run all other wired ports from the new router to the Airbnb rooms. Also setup a different wireless network IP for the Airbnb's wireless. This would at least isolate your personal network from the Airbnb's network.

This should be easily solved as business do this all the time.

The only way this might be safe is a classic "three router solution". If the router they are using connects to the router you are using then there is no security. The internet connection needs to go to router 1, which is set to use a unique non routable IP address, like 10.0.0.x. The guest suite router is hardwared to router 1 and uses its own non routable IP address (like 10.100.100.x ). Your personal router is hardwired to router 1 and uses a different non routable IP address like 192.168.1.x. Then the guest router and your personal router cannot see each other. If you are just giving them wifi access, just use the guest network on your router for them.

Internet by phone can be horribly expensive to use.

The only way this is safe if the wired connection uses a separate network. This is possible with a Ubiquity router. This is NOT possible with a consumer router, and certainly not with the one you choose. Your Netgear is good, but it does not support separate networks on each connection. Again, if the guests connect to the same network that you use there is no security. None. On wifi you can put them on the Guest network; there is no guest network for wired connections.

So here's a link and a pic of one solution. The IP's are isolated.
