This is the Scottish Linux Users group isn't it?

Just checking. What do you mean they are non-Nat?

If you mean that the router they supply won't do Nat - so what! Set up one box 
to act as a masquerading router for your other machines, or run a proxy on 
it. If you need to run publicly accessible services on the other machines use 
port forwarding. Admittedly there are a (ever decreasing) number of services 
which cannot work in this configuration, but there are a growing number of 
connection tracking modules which eliminate this problem (e.g. for FTP, 
irc....anybody know the status of the h323 module?).

I suppose if the contract specifically excludes you from using your own NAT 
routing attached the connection they provide then morally your bound not to 
use the service (although *technically* it would be nearly impossible for 
them to find out).
