What are the basics of setting up simultaneous OpenVPN client and server instances? I have numerous clients configured, and one server, which work fine by themselves. But if I have the server running and I start a client, the server closes.
At the moment, I have a single interface named VPN which covers an "adapter" tun0. Also, I have a VPN firewall zone for the VPN interface with ACCEPT - ACCEPT - REJECT for Input - Output and Forward (for two-way traffic when I connect remotely to the server).
Do I need additional Interfaces, Adapters or Firewall Zones to support simultaneous client and server instances?
