VPN¶

VPN connection can be blocked by company firewall.

OpenConnect¶

The group name should be put in the authgroup.

Decrease the value of base-mtu if get error: Failed to write to SSL socket: The transmitted packet is too large.

Limitation: It seems OpenConnect CLI does not provide the method to get the VPN connection status in Windows.

openconnect.exe my.svr.com --authgroup my-grp --protocol=anyconnect -u usr --base-mtu=1000 -q --passwd-on-stdin

Cisco Mobile VPN Client¶
