      Dear community,

      My task is to connect different locations of the company I’m working in via VPN. Such connections already exist, but the current router should be replaced by a pfSense.

      Here's the problem:
      I cannot establish an IPsec connection if the remote station has not entered an identifier (My Identifier/Peer Identifier) in phase 1. The current router from Lancom doesn’t seem to use this option, as it holds all tunnels without these options being registered. There is only "No identity" selected. Such an option is not given in the configuration of the pfSense.
      For testing purposes, I have attached the pfSense to another WAN and tried to connect to the Lancom router that I can access. The IPsec tunnel only established as soon as I entered the same identifier on both sides (WAN-IP on both sides). Therefore, I assume that the configurations are correct except for the identifiers.
      Is it possible to establish a connection without an identifier with the Lancom router? Unfortunately, I can't walk to all major customers and ask them to do so. Especially since I don't even know if this is 100% the cause.

      Here are the pfSense logs:
