Ok. We will find it out.
1) Set "Listen 8080" in httpd.conf and start Apache.
2) When you enter http://192.168.16.100:8080
(or simply click on that link) from any of your client PCs, you will receive kind of Apache Welcome Page?
3) You cannot reach http://192.168.15.100:8080
from any of your client PCs (same PCs as above), what is not surprising, because this address is not within the scope of 192.168.16.0/24
For my understandings. I need a short explanation: you must have connected the client pcs (192.168.16.0/24) using a switch, a hub or similar. Am i right? You do not use the draytek router (which usually also contains a switch) to build the LAN for the clients? Is that right?
The Server is connected as well to the draytek router as to the LAN switch (or whatever you use). Is that right?
Are there any PCs connected to the draytek router besides the Server PC?
Next, we have to find out, if Apache is listening on 192.168.15.100:8080. As mentioned above, we cannot use the standard client PCs for evaluating, as these PCs are not in the scope of that IP. Therefore my question above, is there any other PC connected to the draytek? if not, there is no problem. The Server itself is equipped with a keyboard and a monitor (hopefully)? So simply start any browser on the Server PC and enter http://192.168.15.100:8080
- that *should* work and show the Apache Welcome screen (and it should work as well as http://192.168.16.100:8080
Before we go any further, please check that out and answer my questions.
