I've followed guides like
https://openvpn.net/vpn-server-resources/troubleshooting-reaching-systems-over-the-vpn-tunnel/ but am still having trouble.
I was able to successfully configure and it has been working for months but yesterday clients are having an issue with connecting. It appears that the access server and destination server are receiving the packet via tcpdump but the final pass through from the access server to the client is always failing.
Is there a guide for what to include in my post to help diagnose?
Thank you.
