A client is moving to a new office. He is sub leasing space. The office has a DSL connection with a few businesses using the connection in the office. What is the best practice here? Can my client simply bring his own router and run a LAN and WAN without having to worry about security (he would have his own SSID and pw of course). Or should I recommend he get a dedicated connection just for his FMS? Since this connection most likely does not provide a static IP, I will have him use a Dyn DNS service for WAN connections.
