The attached screenshots include the anyconnect version, firewall settings (all off) and the anyconnect adapter displaying the "unplugged".

The other anyconnect adapter status is disabled and you have to enable it and that results in the unplugged status.

Again this is a windows 10 vm on a Linux host and the the vm assumes the state of the host and the adapter is bridged. (see pic)

I hope this helps but I'd rather have an Openconnect solution because, again, this a 127GB anyconnect solution that wont do.

[worldwide1]

All of the above still applies but THIS time I am on the win10 vm.

[worldwide1]

As of this morning,16 Feb 2021, I've deleted the win10vm. Spun up a ubuntu 16 vm, install openconnect but it failed, after ctl+c, with "Failed to obtain WebVPN cookie" too.

[bigevilbeard]

Please try

sudo openconnect devnetsandbox-usw1-reservation.cisco.com:20149 -v --no-dtls -u {username}

Hope this helps.

@worldwide1 sandbox does not allow URL/Endpoints to return ICMP/ping. This is within the security posture of the sandbox design. I tested your active session and this connects with success.

Hope this helps.

Could also be worth looking to see if the ports are block somewhere. The port range will be anywhere from TCP 20100 through TCP 20354. You can check this using TCP traceroute for example (use your VPN headend and port details provided in the email you recieved)

@worldwide1  so in the use example one, traffic being dropped at CYXTERA-COM.ear2.SanJose1.Level3.net (4.16.45.254) and the other traceroute, it is not leaving the local network, no route etc... I think this explains why you are getting the 'no internet message' here.

Hope this helps.

[worldwide1]

Reading this (see pic) due to your help.

Thank you very much.

[worldwide1]

I've also no problems spinning up that win10vm to chase down the "disconnected" cable feature?

Let me know.
