This really proves how ignorant I am of networks: at my workplace I have a network with a couple of PCs, a network printer, a home server and a router (a crappy business livebox provided by Orange).
I did set up the Home Server to be accessed over the internet and it seems to work fine (except that the Orange router is so bad it does not support uPnP and I had to configure ports manually).
The problem is that I don’t know how to mimic the access to the home server from the internet without physically being outside of the network. This is annoying as sometimes I want to test settings and I have to go back home to do so. Is there a simple work around?
