Absolutely..  Most networks have NAT routers setup on their perimeter, along with the firewalls...

You got some reading ahead of you, that is for sure..  hope you are up for it..  :)

And once you configure your trust relationships, certainly, they will work through the routers also.

Ok but this mean that the only way to replicate two domain controllers with nat in the middle is to use ipsec?
is the only way?
are there some improvements with 2003?

No, but if you do not use IPSEC, then you must open your firewalls to RPC traffic, and I would never suggest that.  

I believe that W2K and 2K3 use all the same technologies for replication...
