Description

Hello All,

I just updated to the newest dev build and connected to it remotely and had a shocking supprise.  For some reason when I go to google and type "what is my ip" I get an IPV6 address that my cell phone is using which is connectd through a hotspot which is connected via wifi to my laptop.  This laptop then has an openvpn UDP tunnel into my other site's network and all traffic should be forwarded through the tunnel and out that server but unfortunatly it is not.  I only use IPV4 except on the cell phone where it obtains either IPV4 or IPV6 which should be no issue since the laptop and pfsense are not setup to even use IPV6.

In my openvpn settings which have not changed through many many upgrades, I have the following options setup which makes me worried there is a bug and leakage is occurring. "Force all client generated traffic through the tunnel" and "Don't forward IPv6 traffic" options checked as well as firewall rules to drop all IPV6 traffic inbound and outbound.

Please see my version information below:

If needed I can provide any debug dumps you may need, just let me know and I will send them. Greetz to all the devs that contribute to this wonderful project. Thanks! -Ereb0s
