Gowin R86S Bridge LAN / Dual LAN interface with same IP subnet

[kwokmaster]

Hi, I am currently using Gowin R86S with OPNsense installed. I am using the most basic version, with 3 ETH ports. ETH0 is now WAN and ETH1 as LAN. I am wondering how to utilize the other port and set it as LAN2, with the same IP subnet with my existing LAN interface.

i.e. My LAN is now 192.168.1.254, DHCP leasing 192.168.1.xxx to my devices, and I want to make LAN2 the same IP (or probably same subnet?) with it, and share the same DHCP leasing service.

Thank you in advance!
