By default, anyconnect clients will drop all traffic of a given IP version if there is no IP address in that version assigned to the client. The client-bypass-protocol option, if enabled, will send an extra header to the clients telling anyconnect client to bypass VPN tunnel if there is no IP assigned. No impact for openconnect clients, this header will simply be ignored. Signed-off-by: Florian Domain <f.domain@criteo.com>
