A week ago I purchased an VPS. The first few days I was having trouble to set up an outgoing connection on the VPS. Eventually it turned out to be some misconfiguration of the server where the VPS is hosted on.
Since then I have installed the apache server, but I'm still not able to access the apache server from an external computer. I already have contacted the provider, but they haven't replied yet. To speed things up I was hoping someone could check my configuration to be sure nothing is wrong with it.
To be sure I posted all configuration and information that I think would be important. Please contact me if you need more information.

So now I've listed all the generic information, here comes all the configuration related to apache. (I have omitted the comment to keep it as small as possible

Now, so far the configuration. Maybe some more info of interest. If I browse to the VPS from my local computer. The browser displayed an '503 Service unavailable' message. I tried to browse the VPS this morning again, but now I'm getting an '504 Gateway Time-out'.
If you spot any misconfiguration or other problem, please post an reply. Thanks in advance!
