IPSec VPN Configuration for Example 3
After the private subnets, device, and user account configuration in “Virtual
Network and Device Configuration for Example 3” on page 397 is completed,
a VPN connection must be created. With a virtual network, only one IPSec
VPN connection must be configured to create the IPSec VPN tunnel from the
user’s workstation to “sp1,” “sp2,” and “sp3,” which are on both private
subnets in example 3.
Configuration of “connSub2” would be still be needed as in “IPSec VPN
Configuration for Example 2” on page 385, because the only way a user could
contact “sp4” would be through the private subnet IP.
The values used for enabling an IPSec VPN connection are the same as in
“IPSec VPN Configuration for Example 2” on page 385, except the OnBoard
administrator must configure the Left subnet: by entering 172.20.4.0/22 to
configure the connection to the virtual network.
The following screen example shows the configuration on the Web Manager
Network → VPN connections: IPSec Add new connection dialog for a
connection named “connVirt,” with the values specified from the previous
paragraph.
