OpenVPN client static ip CSO not working

2.3.1-RELEASE-p1 (amd64)
built on Wed May 25 14:53:06 CDT 2016
FreeBSD 10.3-RELEASE-p3I'm using OpenVPN with LDAP authentication.
my network design uses two internal networks
192.168.248.x/24 network
10.0.0.4/30 network10.2.0.0/24 network for OpenVPN clients
Connection using Windows 7 client (OpenVPN client) works fine. Client traffic is tunneled across the vpn.I' trying to set static ip to remote users based on X.509 common name to restrict network access based on source IP address.
If I set a diferent network (10.3.0.0/24 or 10.3.0.0/30) on CSO to a User, connection is not working
If I set same network on CSO 10.2.0.0/24 connection is working, but client gets ip address 10.2.0.0 and DHCP server informed to client is 10.2.0.254. If I ping from OpenVPN server side to Windows client it works. I can also browse SMB resources.
If I try to set static IP using advanced option it does not work and ip 10.2.0.0 is set to windows client:
ifconfig-push 10.2.0.240 10.2.0.1;this is my OpenVPN Windows client connection log:

Hi man!
Same problem…dunno how 2 fix it. -
Well, I've found how to make it work, but not in subnet mode.
I've set openVPN Server config topology in net/30 mode. I've used a 10.x.x.x/16 subnet.
Later, in CSO Tunnel Network use a /30 per user.
10.x.x.0/30, 10.x.x.4/30…10.x.x.252/30Client wil use second usable address in subnet, router uses firstone usable. I'm loosing 3 address for every client to use, but using 10.x.x.x/16 you can define more tan 16.000 remote users.
Later, with firewall rules you can tuneup user Access based on their ip address
hope it helps.
