With other appliances, this is called "Walled Garden."  In m0n0wall, you 
must turn on captive portal.  You then upload a web page with a link to that 
website.  Then place the ipaddress of that web site in the list under the 
"allowed IPs" tab of the captive portal page.  Anything on that website that 
calls another website (like advertising or third party cookies) will not 
work.  This may not be a bad thing. :-) Good luck!
