Static Routing

Hi there!

Just wondering if someone could help me out. I currently have two connections, and I'm hoping to combine them into one. (two connections is a bit overkill

)

The first is a DSL connection, with a PC running Linux connected directly to the DSL modem and PPPoE Authentication. With this connection, I have been assigned 5 static IP addresses from my ISP. This connection is currently working fine running a web server, ftp server, etc. 2 of the 5 IP addresses are not currently in use. The netmask is 255.255.255.248

The second connection is a Cable modem connection, connected through an SMC Wireless Router, with several PC's connected on the LAN. Some wired, some wireless. This is a dynamic IP, and running NAT with some Port Forwarding for special applications.

I'd like to drop the second Cable Modem connection, and move the router to work through the DSL, without disrupting the DSL functions that are currently running. Can I do something like:

Code:

 DSL  ___ Linux ___  SMC   ==== Internal
Modem	  PC	   Router	  PC's

If I add a second NIC to the Linux PC, can I assign one of the unused IP's to the SMC router, and let the router handle the internal PC's as before? What would be the configuration of the SMC (IP Address, Default Gateway, Netmask)? Do I need to change anything on the Linux box to pass the IP over to the SMC? Can both incoming and outgoing connections reach the router?

Thanks in advance!
