ERR_CONNECTION_TIMED_OUT

What? Just change virtual mac address to all interfaces and everything complete gone. Can not even access web  on 80 port. How to fix from cli command?

It seems emu0 interface is gone? What? Entire interface can not work at all. How to fix this with cli command?

Delete the ARP cache on the systems you are using to access the firewall.

How this is related to hardware problem as missing entire interface - WAN?
Now WAN is assigned to different interface, different hardware. My emu0 is missing at all.
Also, how to clean this arp with command?

Delete the ARP cache on the systems you are using to access the firewall.

revert back old mac
then restart

then call from cli:

Code Select Expand

ifconfig em0
dhclient em0

still can not get interface to be shown in opensense top interfaces list. Then add new redundancy virtual interface as second wan. After rebooting I can get enter into router and switch back to original interface from em1 to em0.

At the end remove em1.

It was really hard... Something is totally wrong with this mac updates.

Could you describe your setup in more detail? With my hint about ARP caches I was simply referring to MAC address changes. If the MAC address of "anything" changes and you cannot reach that "anything" from your desktop, then e.g. on Mac OS, you need to type:

Code Select Expand

sudo arp -d -a
to clear the ARP cache.

Are you running a virtualised OPNsense? What on earth are you doing? What do you want to achieve by changing MAC addresses?
