My OpenWRT address is connected with WAN to a fiber ONT and receiving a public IPv4 address with DHCP. It appears that my ONT web status page is accessible on 192.168.4.2 on port 80 (I can ping this address).
Is there a way to assign an additionnal 192.168.4.x address to my WAN for access to my ONT web status page without loosing my public IP address? Some kind of Alias. I don't see how to do it in LuCi, maybe it is easier with command lines.
