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.
