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
On the router, if you issue a sh ip route, can you see an entry/entries for your (NATted) internal network(s)? The next hop should be your fw external int - I would imagine that is how it is routing traffic to your fw rather than the wireless device.
I think the first poster was suggesting you have a static route to the NATted address, since it will be hitting the external interface of the fw.
