@smokinjo said in Updating pfsense before using as firewall?:
Can I just connect it to the local network and log in? Pfsense will be behind the firewall, but updating things should work fine.
Yes, as long as there is no subnet conflict between the WAN and default LAN (192.168.1.1/24). If your existijg LAN is already using that you would need to set a different LAN subnet in pfSense first.
