B.2.3 Frequently Asked VPN Questions
The following are common questions that arise when configuring a VPN tunnel.
• Question 1: Does the access point IPSec tunnel support multiple subnets on the
other end of a VPN concentrator?
Yes. The access point can access multiple subnets on the other end of the VPN Concentrator
from the access point's Local LAN Subnet by:
• Creating multiple VPN Tunnels. The AP supports a maximum of 25 tunnels.
• When using the Remote Subnet IP Address with an appropriate subnet mask, the AP can
access multiple subnets on the remote end.
For example: If creating a tunnel using 192.168.0.0/16 for the Remote Subnet IP address, the
following subnets could be accessed:
192.168.1.x
192.168.2.x
192.168.3.x, etc
• Question 2: Even if a wildcard entry of "0.0.0.0" is entered in the Remote Subnet
field in the VPN configuration page, can the AP access multiple subnets on the
other end of a VPN concentrator for the APs LAN/WAN side?
No. Using a "0.0.0.0" wildcard is an unsupported configuration. In order to access multiple
subnets, the steps in Question #1 must be followed.
