Need some help configuring my PIX 501.

I have a small network with 7 users connected to a windows 2000 server that connects to the internet.

Trying to set up network to access the internet through a T-1, we currently have DSL that routes through a gateway address.

my setup is like this:  server----->Pix 501 ------>Cisco 2431 Router --------> Internet

Below is my setup so far, not sure what elements I am missing?

Thanks for the help.......

device1(config)# show route
        outside 1 OTHER static
        outside 1 CONNECT static
        inside 1 CONNECT static
device1(config)# show config

Looks fine to me, what is not working now ? I see that you are natting using the PIX outside interface address, have you configured the router yet ? If so config ?

I'm not seeing a reason you need this line in your config
nat (inside) 1 0 0

Also, I noticed that the IP assigned to the pix is the first useable IP of your range you have.  Typically this is assigned to the router. Just double your router for the IP there.  If that IP is correct, then fix
route outside 1
as the IP you use for the next hop is the same as assigned to your outside interface.
You either need to change that to the correct IP or change the outside interface of your pix to

I can not connect the network to the internet with this configuration.

 Was not sure how to delete the nat (inside) 1 ?

My network connects to the internet through the gateway ip  Assigning this ip to the PIX may not be correct?  I know the network looks for the device assigned with this address.

Also in the past I needed to disable dhcp on the DSL router currently connected to the network, do I also have to do this on the PIX?  If so, what is the command line that I should use.  

I may also have to talk to the T-1 people and have them reconfigure their router (cisco 2431) to disable dhcp also?

Anyway any help or suggestions you may have would be greatly appreciated.

Please draw a network diagram with ip addresses in it here and then post the router configuration as well.

What I'm saying is that internet traffic won't work because of this
ip address outside
route outside 1

You are saying PAT all the inside addresses to, and that the default route is also that IP.  Obviously this cannot be
