If you followed the setup instructions in pfSense Setup: Part One, pfSense should be running and accessible via the web interface at 192.168.1.1 (or another IP address if you assigned a different one). You should be able to log in using the default username (admin) and password (pfsense).
You will want to change some of the basic settings in General Setup. In the web interface, browse to System | General Setup. At “Hostname”, enter your hostname (the name that will be used to access the machine by name instead of the IP address.
Below this, enter your domain (Domain in the General Settings).
DNS Servers can also be specified. By default, pfSense will act as the primary DNS server. However, other DNS servers may be used, and the place to enter them are in the four boxes for DNS servers.
Check Allow DNS server list to be overridden by DHCP/PPP on WAN. This ensures that DNS requests that cannot be resolved internally are passed on to the WAN and resolved by the external DNS servers provided by your internet service provider.
Next, select the correct time zone; you probably want to leave the default NTP time server as it is.
Next is the theme, which allows you to change the look and feel of the pfSense web GUI. You can probably keep the default theme, pfSense_ng.
pfSense’s User Manager, which has been part of the pfSense web GUI since version 2.0.
NOTE: You probably want to change the admin password. You can do this under System -> User Manager. Here you can change the admin password, add new users, and delete users, including the admin.
That’s it for the General Setup within the web GUI. In pfSense Setup: Part Three, I will cover how to configure the WAN and LAN interfaces using the web GUI. Part four will cover configuring optional interfaces.
