Re: DNAT problem in Shorewall

I am now getting really confused.

You have three machines in the subnet 192.168.0.0/24

They are:

IP    FQDN                  Description
1     ???                   Linux Firewall/Gateway
100   www.mydomain.com      Linux webserver running apache
?     ???                   XP box

You are trying to browse http on www.mydomain.com.

You have DNS working on all machines. i.e. running "host www.mydomain.com" (or 
ping on XP) on each computer gives the correct IP address of 192.168.0.100.

If you point a web browser on *any* machine at http://192.168.0.100 you get 
your page as expected.

If, on your webserver, you point your web browser at http://www.mydomain.com 
you get the correct webpage.

If, on your firewall, you point your webbrowser at http://www.mydomain.com you 
get the correct webpage.

If, on your XP box, you point your web browser at http://www.mydomain.com you 
get an IE error page about not found or some such.

If these statements are correct, then your problem is with XP.

If not, which of the above statements are wrong ? And how are they wrong ? For 
example, saying "doesn't show the page" does not say what the problem is. You 
must get some kind of error - please say what that is.

Finally: Please reply to the list - not to me personally. These lists offer 
others the ability to learn and to add input.
