Ipv6 via Ovpn (Default route?)



  • Hi all,

    pfSense 2.0 Rc3

    I've been able to assign an IPv6 address to a OVPN client by bridging pfSense's Tap interface to an IPv6 enabled router and enabling the option in pfSense to pass ipv6 traffic.

    This works in the sense that the client (windows 7 laptop) gets an IPv6 address from my Subnet and is able to communicate with the world over IPv6.

    The problem I run into is that if the client is already on an IPv6 enabled network that the client seems to prefer to use the physical interface instead of the vpn for IPv6 traffic.

    Does anyone know how i'd go about modifying the clients routing table on VPN connection to ensure the IPv6 traffic goes down the OVPN link?



  • It appears there is at least one solution that's so simple I could kick myself for not thinking of it sooner.

    Setting the interface metric to 1 on ipv6 for the TAP interface on the windows client makes it prefer it for Ipv6.

    Now if only I could figure out how to push that change on connect so I don't have to remember to manually configure it on the client machine



  • Decided to install PFsense with ipv6 support and try and do things properly
