Vuze FAQ

Just like the wide array of routers available to consumers, so too is the list of software firewalls, and each has different features and capabilities. Because of this huge variance, we will again attempt to approach this as broadly as possible. A software firewall can offer the same protection that a router can and it can mimic the symptoms of a NAT error. So why should you use both? A router can only protect you from incoming data on certain ports - a good software firewall can monitor outbound traffic too. Consider this an added layer of security.

If you use a software firewall on their PC, the following information applies to everyone who hopes to fix their NAT error.
* You should never have more than one software firewall installed and in use at any given time (analogy: two drivers wanting control of a steering wheel).
* In order for Vuze to run correctly, access/permission must be allowed.
* If your software firewall has options for a security level, reduce it from "high" to "medium" if it isn't already there.
* Your software firewall must allow "Azureus.exe" access/permission.
