However, I'll need to set up static routes manually anyways for the following reasons: - the VPN server is not on the same machine as the Internet gateway, so I also need to add static routes on the router with the OpenVPN server as the next hop. - I also plan to create VLANS for management, testing and security. I know it's overkill for a home network but it's also a lab for learning so regardless of the VPN I'm going to need to configure static routes. The router will soon be replaced by an Archlinux box. Right now I'm testing network configuration on virtual machines. My current router is an all-in-one residential DSL modem and doesn't support anything I want to do. In the meantime, my OpenVPN server does IP masquerade. Regards, -- Alexandre de Verteuil <alexandre@xxxxxxxxxxxxxx> public key ID : 0xDD237C00 http://alexandre.deverteuil.net/
