OpevVPn Access Server routing table help needed.

Hello,

I have been trying to setup::

Device A (PLC, static IP=10.10.10.11) 
        |
        | eth0 connection 
        |
Device B (raspberry B 3,  Jessie)
        |
        | OpenVPN  Clients
        |
Device C (laptop, Windows 8.1)

The thing is Device B and Device C are OpenVPN clients connected to same OpenVPN access server running on Ubuntu system. Also I am using wi-fi router for net connectivity.

My IP configurations are:

(Device A) PLC ---> 10.10.10.11

(Device B)R-pi ---> 
cat /etc/dhcpcd.conf

interface eth0 
static ip_address=10.10.10.10/24 
static domain_name_servers=192.168.1.1

VPN network IP= 10.8.0.2

(Device C) Windows 8.1 --->
VPN network IP= 10.8.0.5

My current state is:

ip route

default via 192.168.1.1 dev wlp2s0 proto dhcp metric 600 
169.254.0.0/16 dev wlp2s0 scope link metric 1000

172.27.232.0/23 dev as0t4 proto kernel scope link src 172.27.232.1 
172.27.234.0/23 dev as0t5 proto kernel scope link src 172.27.234.1 
172.27.236.0/23 dev as0t6 proto kernel scope link src 172.27.236.1 
172.27.238.0/23 dev as0t7 proto kernel scope link src 172.27.238.1 
192.168.1.0/24 dev wlp2s0 proto kernel scope link src 192.168.1.61 metric 600

What should be the static routes on router, on OpenVPN Server web UI and on server??

Trying to figure this out for a long time now. But no luck. Please Help!
