Network Setup using linksys routers

Hello,

I am trying to set up two routers (with a possible third) to one cable modem. I am using the linksys BEFSR41 and BEFSR41 v3. They will be using seperate public IP addresses.

I owned the the first one and thought I could just hook up the second when I signed up for the second IP. I do not have the funds to buy a "real" router that would be able to handle multiple public ip addresses.

Using a switch between the modem and the routers seems to have done the trick. Althought the connections through the BEFSR41 v3 seem to be slow.

I would like to be able to connect using private ip addresses to all of the computers on both routers.
Can I just run a patch cable to a LAN port on both and have it work?

Is there anything special I need to do in order for everything to work correctly?

If you want all the local computers on one subnet, why do you need multiple external IP's?

I have 3 or 4 routers on different IP's on my broadband, all Linksys, but they all go out to different internal LAN's.

Probably you can interconnect multiple routers on the LAN side but you may have issues with gateway addresses on the computers, particularly if you use dhcp for local LAN addressing. Both routers will try to dhcp an address to a client, and each router will give it's own IP as the gateway.

I have an email/web server on my IP.

I am hosting someone else's email/web server on my connection temporarily and would like to have it on another public IP.

I am also now host to a tenent. In the near future I would like to be able to allow him to use my internet connection but with his own public IP. This way he can host what ever he wants.

I woudl like to have them accessable on an internal IP for administration and game playing.
