I´ve been wanting to set up a public ap and figured I could use my trusty old WRT54GL with DD-WRT and buy another router (with VLAn support) as my main router. The actual sharing would have to be connected over my normal network so I need some way to split the traffic from my normal stuff so not everyone can access it.
Main router ====> switch ====> Public AP ====> My computer ====> My laptop
Is VLAN "safe enough" as a solution splitting the public wifi from my network? Is this possible? Are there any better solutions, keeping in mind new wiring is not really feasible?
