If that is the case then you really shouldn't have to mess around with manual routing tables, at all. You should be looking at the OpenVPN configuration. If I was working on this problem, I'd first shut down openvpn and verify that FreeBSD and OpenBSD can talk along their default routes (it looks like they each have only one nic, so the default routes will be used). Next, after I am able to verify clear communication from both sides, I'd start working on the OpenVPN configuration. When configured correctly the openvpn server will push an appropriate route to the client, and presto! VPN. lane
