NAT slipstreaming is actually a chaining of multiple bugs: 1) using the browser to figure out where to forward malicious packets from the internet in the home, and 2) using it and the address to trick the router to actually "slip" those packets into the home. An attacker still needs to figure out what is the internal IP address of a user's computer inside the home, and this is where the browser comes into play. NAT slipstreaming is a way to trick routers to make them think they are seeing an SIP packet, to make them start forwarding packets to arbitrary devices and applications inside the user's home.

One such example for the latter is the SIP protocol, typically used in real-time audio and video communications (such as chat software or IP-telephony). Two exceptions to this general rule are 1) when the user manually configures the router to forward specific ports directly to the user's machine, and 2) when the router runs software protocols to "smartly" start forwarding ports based on traffic patterns. This means only a user device can make connections to the internet, but not the other way around. One of the consequences of NAT is that a computer on the internet cannot access open ports on the user's machine by default, because the router first needs to be configured to forward IP connection requests from the internet to specific devices in the user's home. They do this to allow multiple devices (computers, smart TVs, smart speakers, laptops, telephones etc.) to all connect to the internet at the same time while still only consuming a single internet address. These routers do a thing called NAT (network address translation), which is a way to map local IP addresses theoretically only known to the user to public internet addresses. Typically the computer first connects to a router in the user's own territory, and it is only this router that is directly visible from the internet. Nowadays, a user's computer is rarely connected directly to the internet. I do think though that TinyWall users are in general somewhat better protected, not because it prevents NAT slipstreaming, but because you will have less open ports with TinyWall and so you will have less attack surface when victimized.

Not TinyWall, and not any other free or commercial software firewall. TLDR Just like any other software firewall on a client machine, TinyWall will not prevent NAT slipstreaming.

Tinywall supported full#

Here's the full changelog for the current version:Ĭlick to expand.This might be an interesting topic to discuss now, so I'll go into a bit more detail than maybe necessary, but at the same time I think this will be useful information for many users. Teething problems of v3 should all be gone, and in case you're still on 2.1.

Tinywall supported upgrade#

I consider TinyWall 3.0.9 to be in a very good state now as far as stability and correctness are concerned, so I can highly recommend everybody to upgrade to 3.0.9. The actual number of changes is somewhat larger, but the other stuff is either relatively uninteresting or completely invisible to the user, like stuff that makes my life easier during debugging that I didn't even include in the release notes.

Tinywall supported password#

If a password is set and TinyWall is currently unlocked, the "Lock" menu option is still available to avoid having to wait out the 10min auto-lock period. Instead, you will simply be automatically asked for the password whenever necessary. Lastly, password locking is now much more comfortable to use, because you do not have to explicitly select "Unlock" anymore from the tray menu before performing a privileged operation. Then there was a performance issue which resulted in the service becoming unresponsive for many seconds (in some cases up to a minute or so) on some computers when network parameters changed. First of all, it turns out automatic rule creation for child processes was broken since 3.0.7, that is now fixed. New version 3.0.9 is up! If I had to, I'd highlight a couple of important changes.
