I create a new group for example Group1,and set the group properties VPN IP Addresses----Subnets assigned to this group (optional): example 192.168.110.0/25
and than set the user:(for example User1 group was Group1 ),then through OpenVpn Connect to connect my server; so it assigned IP was the pool 172.27.240.0/25; It was the VPN Settings---Group Default IP Address Network (Optional) set;
It's very unusual, why the group properties VPN IP Addresses----Subnets assigned to this group (optional) won't work
