This is not a question about Mandrake but i don't know who can help me,

I have a Apache web server inside a firewall and for view a web page i
have to
do 2 distinct things:

1 Outside of firewall

i must give http://external-name/page.html

2 Inside of firewall

i must give http://internal-name/page.html

The question is: How i do for only use the first form?
