OpenVPN Routing issues with Sierra Wireless RV50

  • I am having trouble setting up a site to site VPN between PFSense and a Sierra Wireless RV50 I am using SSL/TLS and have the Tunnel-MTU MSS fix & Fragment Settings from Axelf911's post.
    My Clients connect and pass authentication just fine. The issue I am having is that as soon as I add the Client network in the local ipv4 range on the server settings it locks up the client network. Local devices can't even ping each other. When I remove that all works as expected but I don't have a route to get server-side traffic to client-side devices. So not really useable. Any ideas??
