Network Security: Adding xbox360 live and opening up ports
Posted on 2011-02-21
I have small home office network in a domain controlled by a windows 2003 SBS server. It is protected by a Hotbrick LB2 firewall/router. So far, we have not had any real problems. I believe this is due in part to the fact most ports are turned off, The important ones like port 80 are open. upnp is turned off.
I bought my son an Xbox 360, and naturally he wants to use xbox live. He cannot presently as xbox recognizes that our "NAT" setting is set to "strict." I've researched this problem and MS says that in order to hear conversations and join games, I need to open up certain UPD and UCD? ports.
I can do this several ways, generally opening these ports or do port forwarding to the IP of the xbox unit.
My question is should I. Are there any risks to opening up these ports just to the IP of the xbox or to the whole network generally.
To interested experts, I am also going to post a question about the best settings for the hotbrick LB-2 to provide maximum usability while simultaneously providing maximum security.
