gateway questions

[Brett Wiggins]

Hi all,
       I have set up an internet gateway for my home network and have run into some problems. I got the gateway workibng by adding the following to my /etc/rc.conf.
    
    ipfilter_enable="YES"
    ipnat_enable="YES"
    gateway_enable="YES"
  

I can ping the gateway and internet from machines on the home network but I cant browse web pages or use ftp etc. Am I missing something from my config files or do I need to run another program to provide internet services to my network?
