how to access private network in openvpn

I'm using centos 6 and was able to setup openvpn, successfully connect to it and was working fine. My OpenVPN server has 2 IP (wan and lan). My concern is I can't connect to the servers on the lan subnet. I am not sure if this is because of openvpn config or just routing.

openvpn wan ip = 1.1.1.1
openvpn lan ip = 10.0.1.7

I have servers in 10.0.1.0/24 that I need to access. Can someone help on it?
