IPsec VPNs
WeOS provides virtual private network (VPN) support via IPsec VPNs. A WeOS
switch can act as a VPN gateway in NETWORK-NETWORK and HOST-NETWORK
scenarios. Configured as a VPN gateway, it can be used to securely connect
branch office networks with a central office network, or to serve individual users
wishing to ”dial in” securely over the Internet to the central office network, with
their PC connected at some remote site. The data traffic will be protected by
encrypted tunnels when sent over the Internet. A WeOS unit supports at most 25
simultaneous IPsec tunnels.
