I apologise if this is a silly question, unfortunatly my network skills are, well, crap. Got the Dbox connected to my old router (no firewall), in turn connected to the cable modem. Local network ip's are 192.168.1.x. I can access my Dbox (telnet, http, ftp) from my PC - and the DBox can access the Internet. What i'm wondering is if my DBox is vunerable to the outside world. Test's seem to suggest that it's not. If somebody could briefly explain the basics of this kind of network setup/security it would be greatly appreciated.
