Will try and keep this as short as possible.
My friend has a connection to my server ( Vu duo box ) for some TV stuff and because he is living in a very rural area and is not serviced by any broadband provider I supply him with a feed from my network using a PtP link. He cannot connect to my server at all. If I try his receiver at another location on a different network it connects perfectly. I seem to recall reading in the past that you can have issues with a client box if it is on the same network as your server. At my friends house I use a separate router which issues IP's which are in a different subnet as those on the network which hosts my server, eg IP's of network hosting server 192.168.1.X. IP's issued at friends house 192.168.0.X . It has been suggested that I setup a Vlan for my server but this is something that I know nothing about .
Any suggestion appreciated.
