So far, I have installed OpenWRT in the VM and tried to configure it, but ... already at this point I can’t access the Internet from the LAN device (192.168.2.5). For testing, I still use a MiniPC connected to the router, and the Internet works fine on the host system.
My Vmware configuration (WiFi card not yet installed):

And my OpenWRT configuration (WiFi card not yet installed):

I'm not particularly interested in openwrt, so I can try f.ex. pfsense if it's easy to set up. At the moment, I already installed openwrt on vm and got stuck on network (both on guest and host, I think) configuration. The same, if it is an issue with vmware, I am ready to switch to virtualbox for easier configuration.
