Though I agree with what you said (about openconnect just swallowing the poorly 
configured ip routes and squawking about it), and the patch is done - I’ve 
already sorted out the split routes at the PaloAlto end.  And of course all my 
routes are there now.

I would note that if this second unexpected value is new to you, I am running 
PanOS 9.1.2.  These 9.1 and later releases added a lot of UserID features 
(which I use heavily for my GP clients).  I love the granularity of the access 
control.

I do not use IPV6.  Lemme take a look at that and see if I’m up to tinkering 
with it.
With the ever increasing number of people working from home, I’ve spent a lot 
more time in recent days focusing on granting more and more access.

Thank You again for setting me straight.

Glad that helped. Although it is a bad idea to include non-canonical IPv4 route 
specifications, because we don't know what all other platforms and routing 
utilities will do with them, it would be better for OpenConnect to notice 
these, fix them when it receives them, and warn the user loudly. I've created a 
patch to do that: https://gitlab.com/openconnect/openconnect/-/merge_requests/97

Thanks. Unfortunately, the unknown argument values you have aren't very 
interesting (not your fault of course 😂)…

The first we've seen many times. Still don't have any clue what it means 
(possibly it means “default to using IPv4”, but that's sheer speculation). This 
is the first time I've seen the second one, but it also doesn't mean much.

Really, the only feature of GP itself that we don't understand is how IPv6 
connectivity is set up. It sounds like you have some administrative access to 
configure your VPN. If you're feeling ambitious, try setting up some IPv6 
routes and help us figure out how IPv6 address information is configured, over 
at https://gitlab.com/openconnect/openconnect/issues/79
