Just to be sure: did this work in 2.4.x? Or did this never work?
Did you try "redirect-gateway ipv6" or "redirect-gateway def1 ipv6"?

"redirect-gateway" for IPv4 has two (at least) modes
- default mode:
find out where the current default route points to
remove that route
install a /32 route (if IPv4) for the VPN server to the old gateway
install a new route 0.0.0.0/0 -> tap interface
- "def1" mode
find out where the current default route points to
*keep* that route
install a /32 route (if IPv4) for the VPN server to the old gateway
install two new /1 routes 0.0.0.0/1 + 128.0.0.0/1 -> tap interface
Not sure how stupid our assumptions are here, but possibly "if finding
out the current default route" fails, it might be that we do not proceed
further at all...
As a workaround,
route 0.0.0.0 128.0.0.0
route 128.0.0.0 128.0.0.0
should do the same thing as "redirect-gateway def1" but without the
current gateway check (= will only work if you connect over IPv6).
Thanks for the test results anyway, this is a bug and needs to be fixed
- it probably is not a *new* bug, and might not be fixed in 2.5.0, but
it will be.
