Hostname
name of the firewall host, without domain part
e.g. firewall
Domain
e.g. mycorp.com
DNS servers


IP addresses; these are also used for the DHCP service, DNS forwarder and for PPTP VPN clients

> Allow DNS server list to be overridden by DHCP/PPP on WAN
If this option is set, m0n0wall will use DNS servers assigned by a DHCP/PPP server on WAN for its own purposes (including the DNS forwarder). They will not be assigned to DHCP and PPTP VPN clients, though.
Username
If you want to change the username for accessing the webGUI, enter it here.
Password
 (confirmation)
If you want to change the password for accessing the webGUI, enter it here twice.
webGUI protocol > HTTP     > HTTPS
webGUI port
Enter a custom port number for the webGUI above if you want to override the default (80 for HTTP, 443 for HTTPS).
Time zone
Select the location closest to you
Time update interval
Minutes between network time sync.; 300 recommended, or 0 to disable
NTP time server
Use a space to separate multiple hosts (only one required). Remember to set up at least one DNS server if you enter a host name here!
