PPP link works but none of the routing is working

This is my network setup as it stands.

************
* firewall * 10.0.0.1
************
|
----------------------------
| | ..... |
| 10.0.0.3 10.0.0.254
|
******************10.0.0.2
*linux ppp server*
******************10.0.1.1
|
------------------------------------
| | .... |
10.0.1.2 10.0.1.3 10.0.0.254

where the 10.0.1.xxx subnet is a ppp subnet with 200+ clients all
connected via modems. Currently I can get the ppp link up and running
and I can ping the ppp server but cann't get to anything outside of
that. I need to run NAT so that I can access the ppp client machines
from inside the original 10.0.0.xxx subnet. Are there any great
tutorials or How-to's that relate? I haven't found any relevant docs
yet. Also is there a way to use diald on the server so that it will
call any of the clients when they have traffic? I have seen how to
make the client call the server when there is traffic but is there a
way to reverse this to 250+ different phone numbers?

Enable ip forwarding on your ppp server.
echo 1 > /proc/sys/net/ipv4/ip_forward

Enable SNAT on the ppp server.

iptables -t nat -A POSTROUTING -i $EXTIF -j SNAT --to 10.0.0.2

Thanks, the routing is now pretty much working. I just have some
cleanup left to do so that the links work properly and reliably.
