ESPHome issue with a repeater (NAT)

Just to add a solution that worked for me in order to put a router between HA and my ESP. Here is the config of the ESPHome that is behind the router:

wifi:
  ssid: xxxx
  password: yyyyy
  fast_connect: true
  use_address: 192.168.0.144 #this is the WAN IP of the router.    
  
  manual_ip:
    static_ip: 192.168.4.144
    gateway: 192.168.4.1
    subnet: 255.255.255.0

On the router, you need to configure port forwarding for 6053 and 8266 ports.

When integrating the ESPHome device in HA, I use the WAN IP of the router.

I am using this w/o problems for 2 years now.

Hope this helps.
