What I can ping
Host A -> Host B
Host B -> Host A

Host A -> Router B
Host B -> Router A

Host A -> OpenVPN B
Host B -> OpenVPN A

VPN Server -> VPN Client
VPN Client -> VPN Server

What I can't ping
VPN Server to any client side host local address
VPN Client to any server side host local address

I have searched and searched for this but can not find any answers. Why can I not ping Host B from my OpenVPN server?

I figured it out.

I didn't have routes configured in my routers for the tun0 network (10.0.1.0/24). After I added those routes everything works now.

Thank you.

For configs that are sent to each client, I had to add the following line.

push "route 10.0.1.0 255.255.255.0"
