Our intent is to configure multiple remote sites with wireless to use GRE tunneling back to an optional interface on a pfsense cluster and authenticate via a Captive Portal. Our tunnel will consist of one OPT interface on pfsense tunneling to a router or layer 3 switch.
I have a test bed set up with an end-user, going through an access switch to a layer 3 device (where the tunnel is active and actually appears to work) to another layer3 device to the LAN interface of the pfsense device where the GRE tunnel ends at interface OPT1. From the end-user, I can ping the LAN interface of the CP and by using the tracert function, it goes through the tunnel. Our issue is getting the Captive Portal to redirect. We are using 2.0-BETA4 (i386) built on Mon Sep 27 04:12:19 EDT 2010 FreeBSD 8.1-RELEASE-p1 <http://172.31.180.3/> When a web page is called, it will with pass me to the web page if local or timeout if remote. The reason for a timeout if we call www.pfsense.org<http://www.pfsense.org> is that we do not have any nat set up at this time. When we go to www.uthscsa.edu<http://www.uthscsa.edu>, we get a web page. I have cleared cache and arp on the end-user device but this still continues. Does anyone have any ideas? Remember we would like to do this with multiple GRE tunnels as well. Thank you Dwane
