• UPnP Disabled = Fucked Up Internet
    16 replies, posted
What have I done? I went into my Router configuration (D-Link) and disabled UPnP. I didn't click anything else, and saved the changes, now I can't connect to the internet through my router, but I can through my modem. If any more details are needed, go ahead and ask, because I would be glad to go ahead and answer them.
Tried re-enabling it? :v:

[QUOTE=Yzooo;30973433]Try reseting the router to factory settings?[/QUOTE] I would, but I would have to wait for my dad to get back home so I can ask him, since you know, he has things set up on there. (Could just contact me on Steam you know)
So just wait for him ?

If you have to ask your dad to reset the modem then why were you messing around with it in the first place?
[QUOTE=Encryption V2;30973836]If you have to ask your dad to reset the modem then why were you messing around with it in the first place?[/QUOTE] It's not that I have to ask him, it's that he has multiple wireless networks he has set up and I want to make sure he knows I'm doing it. The reason why I changed it is I didn't think disabling UPnP would mess up the whole router. I guess I was wrong (and now I won't fuck with things I'm not sure about).
disabling UPnP shouldn't break it If you can no longer connect to it (and you're sure that you are using the correct ip in your address bar) you might have to reset it to factory settings. You can try simply restarting it though and attempt connecting again.

I just experienced the same problem on an SMC router. I pressed the power button to turnoff the router, pressed it again to start the router again and it worked. uPnP was still disabled, and all is working fine now.
[QUOTE=Hyzo;30973257][b]Why[/b] would you disable UPnP?[/QUOTE] UPnP is a network discovery service. By default, you should keep it disabled because it has so few uses relative to how big of a security hole it is. It was basically designed for easy file sharing on older versions of Windows, media streaming (over LAN) and some types of bittorrent connections. When UPnP is enabled, it basically turns into a security vulnerability. There is no central authentication mechanism, and authentication is optional. It's also completely up to the clients using the protocol to implement their own auth stack. The problem with this is that implementations can vary wildly and in themselves have more security vulnerabilities. Another worse vulnerability is that attackers on the WAN can use UPnP to port forward to a LAN machine and basically have full access to it. This can be accomplished by visiting a compromised or malicious site that uses Flash or Java to initiate the UPnP port forward mechanism. TL;DR UPnP is an antiquated and almost entirely useless protocol and should be disabled.
