adding only specific IP in VPN settings

mahak

Hi,

Can anyone tell me if we can add only specific IP address instead of subnets in the VPN settings under Routing.
Under the below box in admin console-

Specify the private subnets to which all clients should be given access (as 'network/netmask_bits', one per line):

Also if cannot be done is there are other possible way to include only specific IP address rather than subnets in openvpn allowed connections?

Thanks in advance
