i think port 8080 isn’t a correct asnwer
because i have a RB connecting to 2 routers
the gateway of the first router is 192.168.1.1
the gateway of the second router is 192.168.2.1
so when i use the code
ip firewall nat add chain=dstnat dst-address=" Public IP" dst-port=8080 action=dst-nat to-addresses=192.168.2.1 to-ports=80
i accessed the first router not the second
but when i used that code
ip firewall nat add chain=dstnat dst-address=" Public IP" dst-port=80 action=dst-nat to-addresses=192.168.2.1 to-ports=80
i accessed the second router
so i think it’s port 80 not port 8080
