SSL VPN
This chapter describes the WeOS SSL VPN support. The WeOS SSL VPN is based

on OpenVPN
, and WeOS units can act both as SSL VPN server and client. With
the WeOS unit configured as an SSL VPN server gateway with layer-3 VPN in-
terface, it is typically used in HOST-NET VPN scenarios where various SSL VPN
(OpenVPN) clients can connect to the WeOS unit. The unit can also be used both
as VPN server and client gateway in a NET-NET VPN scenario, using layer-2 VPN
interfaces.
