ADSL no-nat

Hello
I have a alcatel speed touch pro adsl modem.
The problem of this router is the NAT table which has only 256 entries.
I thought to install a linux firewall no manage the NAT.
The question is: is it possible to run the router in no-nat considering that
I'm connected with pppoA and 1 dynamic ip?
When I was using ppoE the ip was assigned directly to the machine. With
pppoA the ip is assigned to the router and in this case I suppose I cannot
make it work with no nat. What do you think? Do you have any suggestion to
solve the problem?

Personally I don't bother with an off the shelf router, just use my old
linux box to drive the line. Handles NAT, firewalling, port throttling and
forwarding quite nicely.
It's only an old P166 and should've been skipped years ago, still doin' the
business though.

Seriously, use your linux box to drive the line with a modem and ebay the
router. Let some poor microserf use it

If your router has PPTP support then you are in luck as the IP address can be
'exported' to your linux box relatively easily, however the speed touch pro
is an el-cheapo modem if I remember correctly I probably will not do this.
What it will do however is something (incorrectly) called a DMZ which pushes
_all_ traffic back and forth to a particular private IP address, no IPMasq
tables no nothing. Sure you would technically have below, but it should
work.
