details.
Delete a local subnet—Highlight the subnet you want to delete
and click Delete to delete an existing entry from the Local Subnet
List.
Important: The client machine’s IP address should not match the internal network’s
subnet, as this configuration could cause internal routing and connectivity issues.

Modify Virtual/Local Subnet window, follow the steps below.
1. In the Virtual/Local Subnet field, type the IP address that will be used to
define:
For the Virtual Subnet field—The network portion of the IP
addresses used in the client address pool.
For the Local Subnet List—The network portion of the local
network that will be made available to the VPN clients.
2. In the netmask field, specify the number of bits to use in the network
mask. The network mask specifies the significant portion of the IP
address.
