If I add something like push "route-ipv6 2000::/3"; to my custom options it will get IPv6 to work though the tunnel, but that's kind of a hack. I'm guessing the default IPv6 gateway doesn't get pushed out upon connection.

(Note: Can someone with access please correct my spelling errors in the title?)

also should fix the show/hide of "remote networks" fields accordingly while doing this, so only v4 shows/hides with the v4 redirect-gateway checkbox, only v6 with the v6 equivalent.

You can just add a 'push "redirect-gateway-ipv6 def1"' to the server's advanced options to accomplish that.

Not true.
This is NOT working, you have to add push "route-ipv6 2000::/3"; to get it working.

then that option is broken in OpenVPN itself in your case, and you should report it there.
