P2P openvpn NAT and firewall rules

[jonna99]

Hi!
I need help configuring firewall rules for openvpn, peer to peer, tls.

Prerequisite:

• P2P already established between my two Pfsense firewalls.

• Have access to all necessary networks and clients in both directions without problems.

My problem:

• I want to force one (1), only one, of the clients on the remote side to only use the server side's public IP address for internet access and not "surf" out to the remote side's public IP.

I have searched for solutions on the internet but have not found any solution unfortunately.

So if anyone has a good idea and maybe a guide I would be grateful.

Thanks
Jonna
