Local / Access
This used to specify a local host or subnet which will be reachable by the
tunnel. It is entered as an IP address followed by a slash followed by the
number of significant bits in the entered IP address (i.e., 192.168.41.9/32). To
allow access to only a single host, specify 32 in the bits portion.
