How to set up ping between computers inside Openvpn?

Question

openvpn

Good afternoon. The OpenVPN mesh has been raised, several computers and a file server are connected to it. There is a ping server to computers/dumps, from computers to computers/file dumps - no. The issue is not in the configuration files - before, when the server was "clean", the pings worked. Now ispmgr, docker and other evil spirits have settled there, and ... That's it. What is this "evil spirit" cutting off?

Answer 1

1. Check if there is a parameter to the OpenVPN config client-to-client
2. Check FORWARD firewall rules, it should be allowing between subnets
