F5 VPN set-up plug-in for Firefox, to support dial-factor authentication, fails without some manual help.
Although the server host is visible with a v6 address in DNS, the plug-in fails to connect to the server. Inserting the IPv6 address literal into the URL makes it connect. Again, selecting YubiKey as the secondary auth again fails to load the page. Supplying the v6 literal allows to load the page, collects the credentials and successfully establishes the tunnel. So, this animal can be educated to do what is needed, but it needs manual intervention. Wilfried
