Router/modem not working for external access to internet

Hello all.  I recently had a netopia router go bad and att does not seem to have a replacement.  The only part not working on the netopia router is the internet access.  ATT had me completely reset the netopia and now I have lost all the configuration.  Long story short - after 6 hours on the phone with ATT and them recommending me a modem/router for a home, it still not working.  Original set up - internal network with 20.0 ip addresses and have a windows 2003 server - one with a public ip address and one with a private ip address.   The public ip address has an internal default gateway.  I have the server public ip address connected to the router and another cable from the old netopia to a switch which allows all users to connect to the internet.

The internal connection on the netopia is still working, but cannot get any internet.  The tech had me change the default gateway on my server to the default modem/router 192.168....  I could not get this to work by changing the gateway to that ip address on the server.   What can I do?  ATT tells me they no longer make the router that I need, any recommendations?  I am looking for some help on this.

Not sure on how you make the connection to the internet.
If it's ppoe you need to enter a username and password in the router for it to make a connection to the internet.

There is a username and password set up on the router to connect to the internet - the way it is set up is there is a public ip assigned to the router.  There is a also the 192.168... default gateway which will notwork with the network.  I have everything set up for the default gateway on the server to go to 20.0.0.254.  When I tried to change that to the 192.168 gateway, it did nothing.  The problem is I have an internal gateway (private) and private network that needs to connect to the internet.   I have to be able to assign a private 20.0. gateway within the router to talk to the network.

Unless I can make this work with the default gateway not being changed, but it is a different subnet mask as well.

So if I understand correctly:

Router ip : 20.0.0.254
Server Public NIC ip: 20.0.0.x (something)
Server Private ip : 192.168.x.x

your clients connect to the server and the server acts as router?

I inherited this - so I am trying to work with what I have.  Everything is correct except Server Private IP - 20.0.0.216 on the private nic card
Public IP - 20.0.0.10
subnet mask:  255.255.255.0
default gateway:  20.0.0.254

Outside DNS ip addresses

76....

Private IP:
20.0.0.216
subnet mask: 255.255.255.0
Default gateway:  20.0.0.254

DNS server
20.0.0.216

That is the current configuration -

I was able to point the server to the router by assigning a default gateway in the router to 20.0.0.254.  Plug in the public nic to the router and another crossover cable from the router to the switch.  The switch has around 20 users connected and they could all access the internet and network resources.
