I have my Edge router internal interface connected to a switch and also the firewalls external interface connected to the same vlan of the switch.
I also have a wireless router connected to the same VLAN on the switch. The wireless router default gateway is set to my ISP router.
The problem I am facing is I am not able to reach the internal network behind the firewall from my wireless network. I am able to connect to the internet and everything else is fine in the wireless network. I tried creating a static route on my wireless router for my internal network to route traffic to firewall. It still doesnt work , I think its because of the default route I set.
I am wondering how everything else is working fine, all traffic directed to my internal network from internet are flowing through the router and firewall.
This raises a new question to me, how does my router knows, for the incoming traffic it has to direct the traffic to my firewall instead of wireless router.
Please provide me a solution for routing to internal network from wireless router and also if someone could explain how the router passes the incoming traffic to the firewall will be great
