Question : Network Routing

Hi,

I have 3 networks as below:

1) 192.168.1.x/24
firewall at 192.168.1.1. This is where traffic goes to and fro Internet

A router at 192.168.1.200 within the 192.168.1.x/24 network which performs routing to the below:
2) 192.168.2.x/24
3) 192.168.3.x/24

One of my host in the 192.168.1.x network is using Windows. If i changed the gateway to 192.168.1.200, i can ping network 2) and 3) but cant access from Internet even if i added another gateway 192.168.1.1 with metric 2. But if my gateway is 192.168.1.1, i can reach 192.168.1.200 but cannot get routed to 192.168.2.x and 3.x when i ping them.

What do i need to do to be able to be accessible via Internet and get routed to networks 2) and 3)? If i need to set manual routing from the firewall, how to i do it (route what to what on what)?

Thanks

Answer : Network Routing

I would agree with Irmoore. The router needs to do the routing not the firewall. If you add a default route "ip route 0.0.0.0 0.0.0 192.168.1.1" to the 1700 all traffic that is sent to the router that does not have an internal route will be sent to the firewall. If the firewall has a default route to send all traffic that it receives to your ISP all internet traffic will be routed out of the proper interface. All of your internal nodes on the 1.x subnet need to point to the 1700 as their default gateway not the firewall. Keep in mind that the routers for the other subnets need to also have a default route pointing to the 1700 or if you are using EIGRP or a similar routing protocol you could have the 1700 redistribute your default route to the other routers. I'm guessing that you are using static routes since the network sounds pretty basic so default routes should work.
