My router that ran DD-WRT (WRT54G) died recently and I had temporarily replaced it with my LinkSys VOIP router. I also configured that router to use my dynamic DNS service (DynDNS.org). Upon replacing the broken router with a new one and correctly configuring it, I couldn’t get OpenVPN to work. I finally realized that on the server, when it tried to make the connection back to the client, it was using an IP address from DynDNS.org that was created by the VOIP box that had updated it with a local LAN address. So the tip is, make certain the IP address on the dynamic DNS site is correct – I had to log in and change it by hand because DD-WRT said it didn’t need updating, when in fact it did!
