Range in SPD.CONF

[mnsmani]

Is it possible to specify Range in spd.conf instead of full range ?

If it is 192.168.10.1/24 means 192.168.10.1 to 192.168.10.255
I need to specify 192.168.10.193 to 192.168.10.255 i.e 192.168.10.192/26….

Literally, I want to allow only selected CIDR for ipsec and not the entire subnet.

Is this possible ?

Thanks for your time.
