Never Lost Your Vpn Connection (Ipsec High Availability) - ZyXEL Communications ZyWALL 5 Support Notes

Never lost your VPN connection (IPSec High Availability)

Setup ZyWALL VPN with high availability
VPN high availability is designed for securing VPN connections. Usually ZyWALL2 Plus is deployed
at the branch office or as aSOHO gateway to establish a VPN tunnel to the central office. ZyWALL2 Plus
is desgined for IPSec HA as a redundant gateway can be configured.
Previously, when Internet connection on the remote gateway is down, the VPN connection
automatically disconnects. This is avoided with the dual WAN connection feature on ZyXEL security
gateways. When the primary WAN connection is down, ZyXEL's dual WAN connection feature backs up
the primary WAN connection and automatically transfers VPN connections to the secondary WAN
connection. In addition, DDNS is updated to the secondary WAN connection.
ZyWALL 2 Plus, as a redundant remote gateway, provides always-on Internet and VPN connectivity
for network flexibility. You can configure an IP address or domain name depends on the Network
deployment.
