Have the opportunity to connect GPON instead of adsl, but the price for the connection rather big, I decided to connect with neighbours, dividing the costs for connection and monthly fee for three, the channel is also necessary to equally divide by three. Respectively need a router that can keep a 200 Mbps channel, and share it without a problem on 3 vlana, wi-fi is not mandatory. The Protocol most likely PPPoE. It is desirable that a piece of iron was openwrt-compatible.
Was thinking about Samobor on mini-itx with atom and pfsense is also, but still want a finished device.
