There is no firewall enabled on the LAN computers.The VDSL2 router should be set up correctly in Bridge mode because, a few months ago, I had a firewall hardware with pfSense and I did not have this problem. How come?
One thing I never understood: If I turn off NAT on the router, I can no longer access the Internet from the LAN computers. This happens with the old and the new firewall hardware. How come?
With OPNSense, is it possible to configure it so that it also acts as a full NAT for the entire LAN so that I can completely disable the router's firewall?
