The resulting certificate wasn't valid until the local time equalled that of GMT at the time of signing. In my case the reason for this was because the certificate was signed using GMT time, not local time. VERIFY ERROR: depth=1, error=certificate is not yet valid: One thing I should mention! When I first generated the keys I kept getting a "certificate not yet valid error":
In the end you'll have the following files that'll be used for the OpenVPN connection:
Client Certificates & Keys (one each per client).As you'll see there are four steps, and with each step certificates and keys are created: Essentially what you're doing is creating certificates and keys that the OpenVPN server uses to validate clients that connect - nothing more, nothing less. The first step is to generate a Public Key Infrastructure (PKI), the details of which are beyond the scope of this guide instead please refer to OpenVPN's instructions here.At the time of writing this is the latest version available, but in due time even this blog entry will date. Also I should mention the version of dd-wrt that I'm using is v24-sp2 (04/09/11) mega running on a LinkSys E3000 router. If you haven't yet done this please refer to the dd-wrt website for how to flash your router. OpenVPN – Site-to-Site Bridged VPN Between Two Routersīefore I get into the step-by-step configuration I should mention that I'm assuming dd-wrt is already flashed onto the two routers that you intend to use.Below I will show you the settings I used that got things working for me, but here are a few links that helped me along the way (keep in mind they're dated): It seemed most of the information was dated and more complicated than it otherwise needed to be. While in the end the setup for the two dd-wrt routers is simple enough, the reason I made this guide is because I had trouble finding helpful information when I was setting it up for the first time. The diagram above (click for a larger image) shows graphically what the tap bridge is doing, on the right is the “Work LAN” with subnet 192.168.1.0/24, by using a bridge between the two dd-wrt routers the “Work LAN” extends to the left where any computer plugged into the network port or connected wirelessly is effectively connected to the “Work LAN” on the right.
