I also tried to use the ccd with different segment, with config below:

server.conf
client-config-dir /etc/openvpn/ccd
route 10.8.2.0 255.255.255.0

/etc/openvpn/ccd/username1:
Code:
ifconfig-push 10.8.2.9 10.8.2.10

but still getting 10.8.0.x internal IP instead of 10.8.2.x.

Also put in IPtables:
iptables -A FORWARD -s 10.8.2.0/24 -j ACCEPT
