Can't establish OpenVPN site-to-site tunnel
-
I'm trying to setup a site-to-site OpenVPN tunnel between two sites running PFSense. We've setup CAs at each site, and imported the CA from site 1 which is to be the server side. For some reason, the tunnel won't come up, and I'm not really seeing anything useful in the logs.
As a test, I tried spinning up two VMs as an attempt to replicate it and also to rule out any distance-related issues. Same thing. No tunnel established (I check on the dashboard after enabling the OpenVPN widget), but no real errors.
I've also tried just doing the site as a shared key, but I get the same thing.
Output from pfsense2 (the client side) is below;
