what is route on the server-side LAN gateway to route the VPN client subnet

[banto]

HI, i am new to OpenVPN. I need to set up VPN tunnel and access machines in the server's LAN. I have followed all the doc, but i do not understand what i need to do to fulfill:

Next, you must set up a route on the server-side LAN gateway to route the VPN client subnet (10.8.0.0/24) to the OpenVPN server (this is only necessary if the OpenVPN server and the LAN gateway are different machines).
