I have a pretty simple network and have some questions in regards to port forwarding with two gateways. Please see the attached file for reference.
Basically what i would like to achieve is enable port 80 port forwards from two gateways on the same subnet to my webserver. The issue we face is the port forwarding works fine for the default router as it is the default gateway of the network. How do i allow the webserver to respond to requests from the secondary router. Is there a route command i need to add on the primary router so it is aware of the second router, or is the only option to have the second router on a seperate network and install two nic's in the web server
