LinuxQuestions.org - No access to webserver on orange network (DMZ)

I want to access my webserver from the green network.
I have an IP-address on the green network (192.168.1.19)

I can ping the webserver on IP :

Code:

[jonas@jonas ~]$ ping -c 4 192.168.2.3

PING 192.168.2.3 (192.168.2.3) 56(84) bytes of data.

But when I want to access my index.php-page (http://192.168.2.3) firefox tells me :

Code:

Firefox can't establish a connection to the server at 192.168.2.3.

I have an Endian firewall that connects the RED, GREEN and ORANGE network.
All traffic from the GREEN to the ORANGE network is allowed (inter-zone traffic) on the firewall.

Code:

[jonas@jonas ~]$ traceroute 192.168.2.3

[jonas@jonas ~]$ telnet 192.168.2.3 80

Trying 192.168.2.3...

telnet: connect to address 192.168.2.3: No route to host

I am able to access webpages on my webserver itself on http://192.168.2.3/index.php but not from an external host. Though I have "allow from all".

Do I miss something ?
