hello to all:

I have a doubt, I am setup firewall with NetBSD 1.6.2.
This machine has running NAT.
In all the documentation that I have seen he appears this

map fxp0 xxxxxxxx/xx - > zzzzzzzzzz/xx portmap tcp/udp 10000:60000 (this
changes)

My question is Because there is to assign high ports tcp/udp when running
nat?

Thank you very much
