Connection Problems... help!

Yes, that was indeed the problem. Not long after posting the message I found the tun kernel module and loaded it, and now openconnect actually connects!

It seems tun isn’t loaded by default on this QNAP NAS box, although they do kindly provide a prebuilt version, which was nice!

That would appear to be your problem. Is tun built into the kernel? You
do need to have the tun driver somehow, be it built-in or loaded as a
module. Fixing that it outside the scope of the openconnect client
itself! :)

You say /dev/net/tun exists... is it a symlink? To where?
