      Please bear me with me as this is first time settings IPsec.

      My initial problems with setting up my network is described here: https://forum.netgate.com/topic/159307/help-me-add-access-to-ipsec-site-b-via-openvpn-rw-site-a

      I've decided to start a new thread, hopefully attract more eyes to it, as I still have problems (last post in my initial thread)

      Here is the situation:

      Site B is a remote IPsec server, no access from me, so I have to work with what I have.
      Site B is 10.0.1.0/24
      Due to their restrictions the tunnel have to be NATed 10.201.0.0/16

      I have 3 subnets on site A (1 x LAN and 2 x openvpn server) that are added as P2 IPsec:
      LAN: local 192.168.0.0/24 - BINAT 10.201.0.0/24 - remote 10.0.1.0/24
      OVPN: local 192.168.200.0/24 - BINAT 10.201.200.0/24 - remote 10.0.1.0/24
      OVPN2: local 192.168.201.0/24 - BINAT 10.201.201.0/24 - remote 10.0.1.0/24

      It works, but only 2 P2s can be up simultaneously. If the 3rd P2 gets connected, then one of the previous disconnects the connection. As long as there are only 2 P2s enabled, it works flawless.

      Site B have no restriction and we suspect its something with either pfsense or our settings.
      But what could it be?

        Turns our issue was related to network settings. As the remove subnet was /24 and I had 3 local connected to it pfsense did not like this.

        Anyhow, changed all three P2s into a single one 192.168.0.0/16 BINAT 10.201.0.0/16 remote 10.0.0.0/16
        and now it works flawless!
