I have a little problem with a webserver on my Mac Mini (ppc H/w running
FC7)
I'm trying to setup 'gallery' on the Mini.
I have set it the httpd service and configured gallery and if I access
it from inside my firewall all is ok.
It is ok if I use the external address ( of my DSL router)
However if I try to access it from an external web page then it does not
respond.
Selinux is disabled as is iptables for this test.
Here are two ethereal traces. The first is using my DSL modems external
IP Address. The second is access from an external system.
The Netgear DSL Modem is 192.168.1.1. The Mac Mini is at 192.168.1.3

It appears that the DSL Modem is seeing the address of itself and
looping it all back correctly.

I have changed the external IP Address as it is a test system on a
customers site.
So, the requests get to the system but NOTHING appears in the logs in
/var/log/httpd
As can be seen from the first example, the request gets to the HTTPD
server. IN the second, TCP seems to be blocking it.
The httpd.conf is OOTB. ie no changes from what was setup with the
original install. I know that this is going to have to change at a later
date but I want to get something basic working if possible first.
Any suggestions most welcome.
