Slackware 10: Router: Using 2 Nics, 1 Wireless: Question relates to Bridging

I have a linux box with 2 Nics, and a wireless card.  All are detecting and working just fine.

Here is a diagram of my setup.  eth0 will recieve an IP via DHCP from my ISP.  ath0 and eth1 will contain my internal IP scheme (  Because they are both two seperated physically, I will need to bridge them. (I am thinking of this as it is like any typical OTS d-link router you would buy that has wireless and ports all on the same subnet)

            Linux Box
           |           | ath0 (wireless)
 eth0    |           |------------------------
 --------|           |
           |           | eth1
           |           |--------------------------

In my /etc/rc.d/rc.inet1 file, I created this myself and it all comes up alright.

dhcpcd eth0
ifconfig eth1 netmask
ifconfig ath0 netmask

Not exactly sure how to proceed with bridging eth1 and ath0 at this point.  I have a feeling that it will need to take place with NAT?  Any suggestions?

This will sort you out for "MASQ" firewalling.  It's a piece of cake to install

But that only easily works with 2 NICs - still investigating the bridging bit - can't you use different subnets internally instead?
