Problem settings up OPNsense NAT router (No internet for local Windows 10 machine)

Hello,

currently i am trying to create OPNSense NAT router that runs in HA mode. The HA mode is configured and working. The only thing that isn't working yet is that the local machines can't ping to the internet.

The network topology & problem visualised:

This demo enviroment is setup in VMWare Workstation 16 on a Windows 10 host.

The OPNSense firewalls can ping to 8.8.8.8 and use the internet without any problem.

However the virtual Windows 10 machine(10.0.0.100) can't ping 8.8.8.8. But is able to ping the gateway of the VMNet NAT gateway(192.168.17.2).

When i do a traceroute it doesn't pass the LAN interface of the firewall (10.0.0.1). See the imgur link for the tracert output.

I think it has something to do either with my NAT configuration or some routing problem, but i can't seem to figure it out.

Hope you people can help me with this problem.

Thanks in advance for the replies.
