Network Security: Automatic uPNP Support
Adding NAT rules automatically through UPnP service would be also great for home users and probably some other small companies.
For home use it is a must have, all devices (NAS, TV....) have uPNP. So it would be nice but for company's I am not sure if they need that or if it is really secure
Until (if ever) ASG gains *optional* UPnP support, home users could optionally use a higher-end "home" wifi/router and install an aftermarket OS on it, such as DD-WRT. That will provide VPN and many other more professional features, but still give you popular home-oriented features like UPnP.

As Chester Wisniewski commented, I think it defeats the purpose of the firewall as well. So please don't!
But! as 'Anonymous' said, "This would be a great feature to add. I would even be open to paying for this feature as a licensed add-on!"
If people want to pay money to disregard their firewall, be my guest. At least if you paid you háve to know you bought insecurity, right?
I think you have missed the point. These devices are increasingly being deployed at end user's homes. When a $40 Belkin special works better with their Xbox/Apple/Sony device then it's a problem. I don't want to spend my entire life putting in port forwards to make personal devices work at their home but I do wan't be able to offer them a firewall which can do IPSec/SSL VPN and control what access they get back to my work network. Not to mention traffic inspection, web filtering etc.
I'm not saying it isn't a security risk and I'm not saying enable it by default. I am saying offer it as an option to be enabled but with some controls about it. E.g. let only certain IP's request UPnP port mappings, or only certain ports. As some have mentioned identify the requests and admin approve which would be great instead of having to trawl forums to figure out what ports an Xbox uses or the next new device a client has brought home uses.

Implementing something that automatically defeats the purpose of the firewall makes no sense. If you want to allow everything, don't use a firewall.
Would like to see this one as well
UPnP is required fro server 2012 essentials and while you can make it work without it breaks the wizards pretty bad.
Wow, this FMR exists since 2004:
Too sad, there is still no progress...
This would be a great feature to add.
This would be a great feature to add. I would even be open to paying for this feature as a licensed add-on!
For anyone saying that it is a security risk, well it is. However for those saying that it's a reason not to have the feature, well that's poor form.
UPnP is great for home use and ideally you'd have your astaro still setup to do packet filtering and pickup if any trojans were going out based on the signatures.
To put things in perspective, this wouldn't be enabled at a business but for home users. Those who are running Astaro to support remote VPN access it would be handy. A few times now I have had clients tell me their little home billion/netgear router worked better, and it was due to UPnP and automatic mappings for things like game consoles, chat applications and video streaming. Granted most of this can be sorted by adding manual NAT rules, this isn't really feasible when there is a cost associated for someone to go set these rules up, which is then worse when it just "worked" on their home router.
In any case it should be disabled by default but there are options from these comments which could be done to mitigate some of the risks of having it on.
this would be great
having this feature for home users will be perfect and disabled by default
Christian Stubberud commented
This would be nice to have for homeusers. :) And as others have said, it should be disabled by default.
Other firewalls like astaro supports this.
I agree that upnp would be a good addition, especially for those of us who use astaro at home, and also agree it should be disabled by default.
upnp would be great
Jason Kaechler commented
this would be good, but i think it should be disabled by default, and the admin who wants it can turn it on.
I would also love to see this. It is a pain to switch inbound NAT between devices. My Xbox and PC both use 3074 when gaming. I hate having to go in a switch the mapping.
Maybe you could implement an allowed host list and even a list of allowed port for each allowed host. This way I could allow my xbox to open/map 3074 when needed or have my PC do it when needed

the idea of allowing something on the network to punch holes in the firewall without the network admin's knowledge is a bad idea in the extreme.
One thing I've noticed is that uPNP Broadcasts don't work through a bridged interface pair.
