Multiple clients with one server - VPN mode

[FeriX86]

Hi
I was trying to use VPN mode in the manner of multiple clients connect to one server. They all get connected. I can ping the server from all the clients but the server cannot ping all clients. In detail, the server can only ping one server a time and that server is dynamically changed. For example, for a few seconds, client A is accessible from server, after that it changes to Client B and etc ..
What is the problem? How it can be fixed?
Thanks

Currently ctunnel only supports one client per server process.

Connecting more than one client will result in unexpected behavior.

Multiple clients should be supported in the next release.
