Setting up an access point behind my pfsense box



  • Hi Everyone!

    I have just finished installing the newest pf on an atom board with 4 nic (2 via pcie).  It is a great piece of software and I'm glad to continue learning.  Here's my question:  I have the system working in the following configuration with two unused nics:

    modem > pfsense > switch > router (functioning as a full on router)

    I can't access my server from wireless devices as is.  I would like to have the router and my primary server also attached to the pfsense box.  My problem is that I don't know how to work the interface page to make this so.  I have tried a couple things, but every combination kills internet access on the wireless side.  What should IPv4 Configuration Type, IPv6 Configuration Type, IPv4 address and gateway, etc be?



  • tell your router to route everthing via the pfsense LAN IP that it is connected to, for pfsense, it needs to know where to route subnets behind the router, which is via the router IP.

    Why do you have it acting as a "full on router" if all you want is to add wireless?

    When you say "router" you also mean natting?  Yeah your going to have all kinds of issues with that setup.

    To use your wireless router as AP, just change its lan IP to be on the pfsense network, turn of its dhcp server and connect to the router from pfsense via a LAN port on the router = bing bang zoom AP!



  • Thank you for your replies.  I managed to set the correct configuration up by bridging all the internal connections.  I can't get the router to work without placing all the wireless clients on a different subnet, but I am okay with this for now.

    "I managed to set the correct configuration up by bridging all the internal connections."

    What??  If you want your wireless on different segment, then just connect to different interface on pfsense

    example - see attached

    Where your wireless router is just an AP, and in the example might have IP address 192.168.2.254/24 and connected to the interface on pfsense via a lan port on the old wireless router.  Turn off the wireless routers dhcp server and there you go wireless accesspoint.




  • I just did something like that.

    I have pfsense at 192.168.0.1, which routes and does DHCP

    I then have wired connections to two wireless access points.

    192.168.0.2 is a nice Asus which lets you just pick access point mode (automatically turns off routing and DHCP).  The cable is in a LAN port, now the WAN.

    192.168.0.3 is this that I picked up for $12.99  http://www.tp-link.com/en/products/details/?model=TL-WR720N  On it, I just leave the WAN port disconnected and make sure DHCP is turned off

    how about in my case? i have static ip 192.168.2.1 in my LAN? how change my WAP's IP to be on the pfsense network?

    Change your old routers lan IP to be on the 192.168.2/? network your using I would assume /24

    Make it 192.168.2.2 for example unless something else is using that IP.  Can not help you with details because you didn't say what old router your wanting to use as AP.
