OpenVPN S2S - Routing Problem?

[Punkte]

Hello together,

I already wrote in the german section, but until now I could not fix my problem.

I have a OpenVPN S2S Connection to a Sophos UTM9. The connection is up and working.

I have following networks:
UTM9 Clientside: 192.168.50.0/24 (SSL Server - OpenVPN)
Transportnet 10.242.2.0/24
OPNsense client side 192.168.95.0/24 OpenVPN client

I can ping from:
Clients UTM -> OPNsense Clients and Transportnet etc.
OPNsense default adapter to UTM Clients (I guess its the OpenVPN adapter 10.242.2.x)
OPNsense Clients to OPNsense OpenVPN adapter 192.168.95.1 -> 10.242.2.x

I cant ping:
OPNsense clients to Transportnet UTM Adapter or Clientnet of UTM

The interesting thing is, if I switch of OPNsense Firewall (in the advanced setting) I can ping to all UTM Clients.
This is not possible even with each adapter any to any connection allowed on top of the rules.

I guess its just a small option setting which I cannot find. Does anyone have an idea or solution?

What do the firewall rules on your LAN interface look like? Without that information it's hard to help you. My crystal ball is at the shop

Except the automatically generated rules, there are 2 rules:


       Protocol   Source   Port   Destination   Port   Gateway   Schedule   Description    
                                                                                                                           Automatically generated rules   
        IPv4 *   LAN net   *   *   *   *   *                                       Default allow LAN to any rule      
        IPv6 *   LAN net   *   *   *   *   *                                      Default allow LAN IPv6 to any rule      

The OpenVPN & Floating Rule are the same like IPv4, just with Source any aswell.
