The LAN has a the default 'allow' rule letting traffic go any where it wants from the LAN so I assumed if I just made the allow rule on WLAN let traffic in the WLAN only go to the WAN. However when I put in a rule like that it doesnt allow internet access at all. So then I thought well put in the standard allow rule for WLAN and then put in a block rule saying traffic from WLAN isnt allowed to access LAN but then I read the caption below the firewalling stuff on pfsense and it evaluates the rules on a first match basis so my next theory was no good. My last option was putting that same block rule on the LAN interface but that didnt do anything either.
Am i barking up the wrong tree trying to use the firewall rules to block between interfaces? Or is it doable. Do I need to run a squid proxy to do this?
Any help much appreciated.
