Hello everyone,
I have a Novell Server that has been moved from a public ip to a private
one (192.168.0.6). The 192.168.0.xxx segment gets internet access through
a FreeBSD box using ipfw/natd. The Novell server needs to be accessable
from the internet from source addresses 142.42.22.xxx. So I tried to set
up a NAT for it as follows:

natd -p 7500 -redirect_address 192.168.0.6 0.0.0.0 -a 207.24.168.5

ipfw add 10 divert 7500 ip from 142.42.22.0/24 to 207.24.168.5
ipfw add 20 divert 7500 ip from 207.24.168.5 to 142.42.22.0/24

So 142.42.22.0/24 should be able to get to the novell server using
207.24.168.5 as its ip. Using the Windows Client they can connect and see
the NDS tree but when they try to log in the connection times-out. I know
there are some programs that wont work through NAT (like the ones that
insist on reporting back the private ip address). I was wondering if
anyone has had experience logging into a Novell Server with NAT. Can it
be done?

Thank-you
JohnC
