Klausimas
SuperUser skaitytojas user1152285 nori žinoti, kaip saugiai pridėti nesaugių prietaisų prie namų tinklo:
I have a few Internet connected devices that I do not trust as being secure, but would like to use anyway (a smart television and some off-the-shelf home automation devices). I do not want to have them on the same network as my computers.
My current solution is to plug my cable modem into a switch and connect two wireless routers to the switch. My computers connect to the first router while everything else connects to the second one. Is this enough to completely isolate my computers from everything else?
I am also curious if there is a simpler solution using a single router that would effectively do the same thing? I have the following routers, both with DD-WRT:
- Netgear WNDR3700-v3
- Linksys WRT54G-v3
Except for a single computer on the first network, all of my other devices (secure and insecure) connect wirelessly.
Kaip saugiai pridėti nesaugių prietaisų prie namų tinklo?
Atsakymas
"SuperUser" autorius Anirudas Malhotra turi mums atsakymą:
Your current solution is ok, but it will increase one switching hop plus the configuration overhead. You can achieve this with just one router by doing the following:
- Configure two VLANs, then connect trusted hosts to one VLAN and untrusted hosts to another.
- Configure your iptables to not allow trusted to non-trusted traffic (and vice-versa).
Hope this helps!
