Guacamole is installed on a PC behind a Zyxel firewall. Users should connect to Guacamole via VPN and, once logged into Guacamole, log into their PC. However, the firewall cannot handle multiple VPNs. So, I wish to install OpenVPN, possibly on the same PC used for Guacamole. To access OpenVPN I would like to open a set of ports on the firewall to the Guacamole PC only, so that it is not necessary to use a VPN on the firewall.
Do you have any suggestions in this regard? For your info, there are fewer than 10 users and each can only access their PC. Only one or two users should be able to access all PCs. Thanks in advance.
