Non Debian Specific Network Security question
Sorry that this is not debian specific, but on the off chance that someone
does read this, thanx!
I am about to put work onto the internet to run a web server, and for
users to browse the web and exchange email.
I have registered a domain, for example xyz.com
The link will be a dedicated dialup, until I can justify isdn. My isp will
provide me with a static ip. The box on my end of this link will be a
Debian machine. The web server will run on this box. I will use ip
firewalling and masquerading on this machine also. My internal network is
a class A, per rfc1918. I will call this machine www.xyz.com This machine
is dual homed with the ip from my isp, and 10.0.3.254
I dont want users to see a machine one the internal network, such as
applications.xyz.com(10.0.4.1) thru nslookup et al.
My question is: should I run an internal domain server for a made up
domain, such as xyznet, ie the applications machine will really be
I understand that 10.0.4.1 will not be reachable from the internet, but I
do not want anyone knowing about it's existance.
If i run a made up domain internally, www.xyz.com will have to relay mail
to services.xyznet. Also, I assume that ms outlook(i know, i know) will
have to be configured to use xyz.com as the senders address.
Does this make sense?
Thanks in advance!
