OpenVPN site-to-site not working after configuration restore
-
Hi all,
I've a lab with a pfSense 2.4.0 in a VM in VMWare. It is working OK. I am using two VPN site to site using OpenVPN, the lab side is the "server" and two remote sites are the "client". Both are working OK.
Now I need to migrate the lab pfSense to another environment. I've installed a fresh clean pfSense 2.4.0 and after a basic config, I've restored the configuration of the working pfSense. All is restored, firewall rules, NAT, HAProxy, OpenVPN, etc... But one of the two VPN is not working. Both are configured the same way, one is working, the other doesn't.
I am using shared passphrase for both, no certificate is involved. I don't understand why one is working and the other does not.
Any suggestion? Thanks a lot!

Check your settings or might be you didn't configure proper.

These are the logs in the lab side, where the pfSense has been migrated:
