In my configuration, my server's network is 10.1.1.0 and my VPN is 10.1.10.0, in order to access the server side networks, you need to enable the forwarding and masquerading, here's the steps:

$echo 1 > /proc/sys/net/ipv4/ip_forward

$iptables -t nat -A POSTROUTING -s 10.1.10.0/24 -o eth0 -j MASQUERADE
*Assuming your nic is eth0 and your vpn network is 10.1.10.0
