olemus
võrgustatud arvuti konfiguratsioon, mis võimaldab kaugkasutajal krüpteeritud tunneli kaudu kasutada oma asutuse VPN-is olevaid ressursse ning väljaspool tunnelit kasutada kohalikke ressursse;
pääseda Internetti ja/või teise VPN-tunnelisse; suurendab läbilaskevõimet, kuid loob VPN-ile lisaohte

NIST SP 800-113:
a method that routes organization-specific traffic through the VPN tunnel, but routes other traffic through the remote user's default gateway

NIST SP 800-171:
the process of allowing a remote user or device to establish a non-remote connection with a system and simultaneously communicate via some other connection to a resource in an external network
