QEMU NAT with Opnsense

[August8828]

Hello,

unfortunately I have problems get the NAT option with QEMU on my Linux host running. I use Linux as my main OS and it seems like I can not establish a connection over my VMs which use the NAT option.

For NAT, I got assigned the 192.168.122.0/24 network. I can ping it from my Linux host. Unfortunately, when creating either a Linux or Windows VM, the network can not get established and I do not get why. Regarding the routing table, it should use the 192.168.100.1/24 as gateway.

I also use VLANs in my network. X.X100.0/24 is my management VLAN.

Do you have an idea why this is not working?
