I have 4 Linksys WRT310N on my network. One is a OpenVPN server and the others OpenVPN clients. 2 of the clients have DHCP enabled. I also have software OpenVPN clients. The problem is some network clients are using remote gateways instead of the local one. For example in Miami the router DHCP server is 192.168.1.1. A client connected to that router is being assigned a IP by the Houston router, 192.168.1.2, when it should be assigned by the Miami router, to which it is connected directly. How to prevent such behavior?
