The OpenVPN management interface is used heavily by Access Server, but also by many OpenVPN clients. This page tracks the status of IPv6 support in the management interface. Much of the content here is blatantly copy-pasted from cron2's test description with only minor edits.

Current status

What works

The status output displays IPv6 just fine:

	status 0

What does not work

NOTE: These should be split into tickets if we deem them important to fix.

  • Commands "status 2" and "status 3" show a column for "Virtual Address" in the CLIENT_LIST, which only lists IPv4 (since there is just one column), but the IPv6 stuff is there in ROUTING_TABLE just fine. Is this a significant problem that needs a format change (adding one column for "Virtual Address v6")? Update: a patch has been done for this, waiting for review from James.
  • Management command "kill IP:port" will fail for IPv6 addresses
  • The client-pf is not working, but that's larger than "management" - that PF stuff is functionality that is not in the 2.3 core at all for IPv6 yet.

What has not been tested

  • All the config commands should be configurable as if configured in the local config file
  • the management interface itself might not bind to IPv6 sockets
