OpenVPN Support Forum

Hi guys,

I am pretty new to openvpn access. I am trying to create a user group so that I can set some and manage permission for certain users. however once I create a groups and set the password related configuration.. basically;
Local Password Settings
Allow password change from CWS Default Yes No
Enable password strength checking in CWS Default Yes No

I leave VPN Address configuration block empty (since it is optional)

when I click save and update server However get this error

openvpn_iptables_configure: client-side subnet collision between 192.31.255.0/255.255.255.0 'Group-owned subnets for Test Group' and [192.31.255.0/255.255.255.0 VALUE='Global Dynamic Subnets'] (EQUAL)

The VPN Setting Network Address is as follow

Network Address
192.31.255.0/24

Static IP Address Network (Optional)
empty

Group Default IP Address Network (Optional)
192.31.255.0/24

What could I be doing wrong?
