Connect 2 clients from LAN to L2TP/IPSec server simultaneously
Please help to solve the problem. I configured the L2TP/IPSec server (pfSense, latest version). Clients with different IP-addresses on the Internet are perfectly connected to the server. But it was necessary to connect 2 clients from a external large LAN that connects to the Internet via an ordinary router. And these clients have the same external IP address. And it turned out that both can not work simultaneously, either one or the other. How do I get both to connect without connecting the entire network (site-to-site)?
Thank you in advance.
