Specify a VSAP server to be used for accepting from clients or for
connecting to clients. VSAP is a remote socket mapping server
which enables servers to accept a TCP connection via a remote host
as well as to connect via a remote host.
Example:
// VSAP server firewall% delegated -P8000 SERVER=vsap PORT=8080-8090
// accept via VSAP
to provide internal servers for external clients internal% delegated -P8080@firewall:8000 ...
// connect via VSAP,
working as a proxy server for internal clients internal% delegated -P8080 CONNECT="{vsap/firewall:8000}" ...
// accept and connect via VSAP server internal% delegated -P8080 VSAP=firewall:8000 ...
