Hi, all sorry for delay in reply, The services are set up and my ISP confirmed ports not blocked, i have however noticed its always exactly 12 hours after the original start up time, this seems to be when my Wireless LAN IP renews its lease, i do not currently have time to disable the bridges i have setup for virtual boxes, but will try this later today when i get back from work. disconnect issues are happening at 16:09 and 04:09 at the moment. and from what i observed if i restarted at this moment in time it would begin occurring at 07:40 and 19:40. i will post an update later today, hopefully i can test it before it renews this afternoon.

Edit: i will also try connection through wired interface. Tomorrow.
