Site-to-Site OpenVPN with NAT using 2 tomato routers

Hey everyone, so, after lots of googeling and trying I'm turning to you guy's.

My situation is that I have two Netgear R7000's running Tomato 1.40 Shibby (ARM) AIO buids..

My test setup is as following (later the other router is going to ship to another location):

MODEM DHCP: 192.168.0.x

Tomato-A:
-WAN IP: 192.168.0.101
-LAN DHCP: 192.168.1.101-192.168.1.199
-OpenVPN server IP: 10.8.0.0

Server settings:
-Push LAN to clients: yes
-Respond to DNS: yes
-Advertise DNS...
