While there are many methods to accomplish this, a simple method works well for most applications. Internet modem gets connected to router 1 set router one to say 192.168.2.0 remember to change it's default password. Set the wireless to say either channel 1 or 11 (1 & 11 don't overlap each other in the RF spectrum.) You can leave the wireless open to make guest connections easier. Set routers DHCP to say 20 users starting at say 192.168.2.10 which will cause the router to start issuing IP's from 10 to 30. Set the router for DMZ to the highest IP, in this case 192.168.2.30 Connect one of the user ports on router 1 to the WAN port of router 2 configure router 2 for say 10.0.0.0 Change it's password to something secure. Configure the wireless for the unused channel (if router 1 is channel 1, then make router 2 channel 11, this way they won't fight for the same RF spectrum.) If you want to use DHCP set it for the exact number of machines you have on your network this will minimize the chances of more uses. Also config the wireless access for WEP or WPA, and setup the MAC address filter list for all your wireless devices (this will minimize chances of a foriegn machine gaining access to your private network) Even better is to turn DHCP off and "Hard-Code" all your machines for predetermined IP's in the same address range as set above, such as 10.0.1.101, 10.0.1.102, etc. This method makes it difficult for 'guests' to gain access to your private network but easy for them to gain access to the public network/internet. The problem with using just one wireless router is that once someone gains access to your router they have access to everything on the network. Setting DMZ on router 1 tells it where to forward all it's unused port addresses, this should help with applications that require opening ports for incoming traffic such as web-server, game servers, etc. -Jim- Dan Chisolm wrote: > Is there a way to cascade two wireless routers such that each is on a > separate network (security enabled)?
