All in all, not ideal. There are a number of common security risks associated with UPnP that many cite when recommending that UPnP is disabled. Many people refer to this recommendation when citing why UPnP is potentially dangerous. A lot of the problems associated with UPnP threats can be linked to security issues during implementation. Router manufacturers historically have not been good at securing their UPnP implementations, which often leads to the router not checking input properly.
Malicious applications can therefore quite easily exploit bad UPnP implementations to run commands or redirect network traffic. Common malware, such as Trojans, viruses, worms and more, can make use of UPnP once they have infected a computer on your local network. UPnP might allow such programs to bypass security protocols and software that the router would usually block. UPnP essentially assumes that all programs are legitimate and allows them to forward ports.
This is a genuine issue that many are concerned about and, unfortunately, if this is a sticking point for you then you will probably have to disable UPnP. If you were to access a website running a particular Flash applet, that applet can send requests to your router to forward ports. Fortunately, if this does happen to you, having a firewall in place will prevent the attacker from exploiting any vulnerabilities in your network services.
This could end up redirecting your traffic to a different website, setting up endless possibilities for data theft and fraud. Ultimately, it is a matter of opinion. It becomes exposed to public traffic on the mapped port and that is a security concern. The same applies to static port mapping. Security wise, UPnP is not a secure protocol. It uses network UDP multi-casts, no encryption and no authentication. Since UPnP is not authenticated, one computer could request port mapping for an another one.
Interested readers can find many resources about this topic on the Internet. UPnP port forwarding is available exclusively to our Premium subscribers. In order to enable it, please follow the instructions here. In computer networking, network interfaces enable computers to communicate over the network. A typical home setup will utilize one local area connection interface or one wireless connection interface.
Advanced setups might utilize many network interfaces. All available network interfaces should be utilized when an application is port mapping via UPnP. A port might get mapped on multiple routers because of multiple network interfaces involved. I've just downloaded Utorrent and I have to say it is an excellent program.
I followed all the instructions on portforward. I ran the test and it worked ok. UPnP is useful if you like rotating your port, or don't want to be locked into the same rule on the go. Sometimes UPnP is not enabled by default so it's sometimes just easier to forward ports if you're already connected and logged into your router.
For you disabling both of those options will not cause any harm as you're already setup. If you get sub-par performance try it. There's no disadvantage to it Personally I like FORCED encryption and dis-allow legacy connections for the sheer fact that I prefer people I connect to not have to deal with shaping problems if they are apt to happen.
