Add static routes for gif,6rd and 6to4 endpoints
We need to add static routes for 6rd,6to4 and IPv6 GIF endpoints that do 6in4 traffic. Otherwise these tunnels will not work.
Proto41 traffic is stateless and will go out the default route instead of the correct OPT or WAN interface.
Possibly add this in the same place we currently add the routes for IPsec tunnels. Same issue.
