IPSEC Routing from LAN not working

[Jenser]

Hi all,

I have the following setup:

Network A (under my control)
192.168.180.0/24

Network B (not under my control)
we have to access different Servers in this network, like
10.1.x.x
10.192.x.x

I got the IPSEC settings from my counterpart. Connection works without problems.
In Phase 2 Settings I have configured a Tunnel IPv4.
Local Network as LAN subnet
Remote Network as Network 10.0.0.0/8 (since I have to access 10.1.x.x and 10.192.x.x I thought this makes sense).

I checked the Firewall Rules for LAN. Nothing will block the traffic. I also tried to add a Rule to allow it explicitly).

Now when I try a PING, SSH, TRACEROUTE to one of the servers in the 10.x-Network, I will end up in my PFSense. The traffic does not get routed.

I have no idea, what I am doing wrong. How can I find out, if it is an issue on my side or on my counterpart side? Cn I somehow sniff traffic with PFSense?
