Currently my setup is this: Telstra fiber NTD -> Telstra Modem (broadcasting 5ghz WiFi) -> Switch Everything else I have (Ubiquity AP, HP Microserver, Desktop PC) is plugged into the switch. This gives me 2.4GHz/5GHz WiFi and internet access to every device in the house. The Telstra modem provides the routing/DHCP features that I need. What I'd like to do is remove the Telstra modem. My plan is to install some sort of hypervisor on the Microsever and starting using a router OS to manage the internet. Will I need 3 ports on the Microserver (1 for the modem, 1 for the pfsense VM and 1 for all other VMs)? Or is two going to be enough? The switch is managed, but I haven't investigated yet as to whether it has a password or not (bought it from an office that was moving). It's a Cisco 24 port GBE switch.
