Oops, apologies for missing that.
This should probably fix the fact that --mtu doesn't work. Please
confirm, and I'll fix it.

Hm, please could I have simultaneous captures of *both* the tun0 device
traffic, *and* the UDP Internet?traffic between your public-facing
network adapter and the VPN server. Along with the verbose output of
openconnect where it gives the ESP keys I'll need to decrypt the
latter.
Kill the session before you send the email (on general principles you
don't want to be giving out the keys to a live session), and try not to
have any other traffic on the VPN when you do it (partly for ease of
analysis, and partly because you don't want to show me anything else).
You can send that in private mail if you prefer. Thanks.
