Hello,
I apologize in advance if this question has already been answered. I did some Googling and searching of the form, but I'm new enough to FreeBSD that I doubt I am searching for the correct terms.
For cost reasons, I am operating a Tor exit node in a data center that is single-homed on Cogent. Unfortunately, Cogent does not have routes to the full IPv6 internet (most notably Google).
I have been able to restore access to Google by using static routes and tunnelbroker.net from HE, but this is an awkwardly manual process.
What I would really like is to attempt to send all IPv6 traffic to the Cogent gateway and fallback to the HE gateway when I receive ICMP Destination Unreachable from Cogent.
Is something like this possible with FreeBSD (without getting BGP involved)?
For reference, here is my current networking configuration:
Thank you in advance for any help that you are willing to provide!
