| UPNP Setup I believe that I understand what UPNP is, but my router is confusing me. When I go to turn on UPNP in my router, it is asking me to choose an internal port, an external port, and an ip address. I thought that with UPNP you simply had to turn it on and then the devices handled all the port numbers. Why is the router asking me for all of this information? Wouldn't that be the information I would find if I wanted to configure port forwarding by myself under the port forwarding tab? | |

Norman, OK | Re: UPNP Setup What make and model router?
Your right though in that UPnP should just work. | |

| I am using the Linksys RVO42. Here's a screenshot of my UPNP setup page. The two entries there appeared automatically but the instructions in the manual tell me to pick a port number and everything and make my own entries into that table. Should I just ignore the table, as you guys said that the UPNP should work automatically? | |

| While I am not familiar with the router in questions some vendors have begun trying to mitigate the complete lack of security in upnp by requiring the user to specify which ports, etc. are authorized prior to actually allowing a client to open them. While only a small step to rectify the lack of security in upnp it is better then nothing. | |

| Re: UPNP Setup The only reason that I was interested in UPNP is because there are two xbox 360's in my house connecting through one router, causing NAT problems for each system. I thought UPNP would help this, so can I use that tool to disable UPNP on all my Windows computers but allow it for the xbox 360's? | |

| Re: UPNP Setup Okay, thank you for the help. That's the strategy that I will try to implement as well.
Also, I was just wondering, even with all of the Windows XP security updates and service packs, Microsoft wasn't able to fix the UPNP security vulnerability? | |

| Alright, I will try it. Thanks for all the help. It seems pretty irresponsible of Microsoft to just turn on UPNP for everybody.
Also, does the UNPNP program to disable the UPNP on Windows not for Windows XP Media Center? It worked for me on XP Home and Professional but not on Media Center. Is there a reason for that? | |

| said by pandora  :Be careful about network UPnP on your windows PC's. It can create serious vulnerabilities. GRC made a Windows UPNP detection application which has been helpful to me over the years. You can find it here - » https:// www.grc.com/unpnp/unpnp.htm Just curious about what kind of vulnerabilities would exist with UPnP enabled on the Windows PC, but disabled on the router ...
