Hoang, If the Net 1 clients don't know where to route and they send to the router, the router is either going to send a redirect or forward the packet itself(both?). This will have the effect of adding traffic that is un- needed to your network. If this network is small, then it's not a big deal. I would make the default route for net 2 clients, the router and for net 1 clients, the fw. If you have a DHCP environment, this is easy to change. If you have to hand change, then either leave alone, change them all at once or change them when you need to do something else to the client(consolidated changes). As for adding routes to your fw, you should only need to add 192.168.2.0 to the fw route table. The 192.168.1.0 net can be reached directly. Robert - - Robert P.
