I have this scenario
a ISP provided router facing internet doing NAT, it's LAN address is 192.168.1.1
a mikrotik connected to it, fixed ip is 192.168.1.252, doing nat to, it's lan address is 10.0.1.1
There is a long range wifi link in between the routers, but that is working without adding route hops, so this can be ignored.
Now I have a web server at 10.0.1.206
I was looking at hair pin nat, but the router facing the internet seems not able to do it
Also the public internet IP is not fixed ip.
I guess hair pin would only work as the manual says if my out interface address where the public ip address, which in this case is not. Also I wouldn't like this traffic to bounce on the 192.168.1.1 router as it has the wifi link.
I guess router could do kind of NAT so I can reach my web server from within the 10.0.1.0/24 lan using the public IP but I am clueless.
The port forwarding works already, I can reach my web server from the internet no problems.
