Topic # 94339 8-Dec-2011 12:44 Send private message

So I have gone away from IPcop and installed pfsense. Mainly I want to have a play with the captive portal function. so far been quite succesful in making a 'wireless hotspot' type connection. Only problem I am having is I cant block stuff coming from my WLAN (192.168.100.0) to the LAN (192.168.1.0).

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.

Restart pfSense after you make those rule changes.

Although it's been a while since I've setup pfSense, it probably hasn't changed much. I'm sure that it can be done because I had similar setup where I used it as a router with various NICs (obviously, in and out) and WIFI. Plus I managed what was allowed between the different networks and LAN segments. I haven't kept anything but, from memory, there were some similar examples of rules on the web for LAN segmenting, pass through, etc.

It didn't work initially and I spent a lot of time working on it until I accidentally shutdown pfSense. Although I had understood that the rules would take without a restart, apparently that's what was needed.

You'll want to put a block rule on the WLAN interface to the LAN network and then underneatht aht do an allow all to everywhere. That will do what you want.

Worked like a charm. I can understand it now. You set the base allow rule and then just build on that. Thanks heaps!!
