How to set up and send traffic to certain resources through a bunch of pfsense + openvpn config client?

Question

FreeBSD

Good afternoon.
There is a raised gateway on pfsense (distributes access to users on the Internet in LAN);
There is an openvpn client config, there is no access to the openvpn server, since we are only provided with a config;
There are a number of resources that can only be accessed through openvpn;
In which direction to dig, what to study, what to google in order to solve the following problem:
In order not to install this config on each computer, is it possible to somehow install it on the gateway. And when users access a number of resources, did the traffic go using this config and users had access to these resources (behind openvpn)?

Answer 1

Can. Set up an openvpn client on the gateway, raise conn with the server
Next, mark the traffic from the desired network. (Typo when requesting from the network 192.168.0.1/24 >> the desired site is marked)
Next, redirect the marked traffic to the openvpn gateway
