NuFW 0.9.0 is the first release of the development branch. It features quite a lot of brand new things. The most meaningful are the protocol version 2 :
A more evolutive protocol which will be able to support things like application announcement (and thus application filtering)
Authentication is performed via SASL
Encryption is performed via TLS
It now uses username and not userid
and the cache system :
User request is only performed at the authentication stage
A cache has been put on acl decision. Benches show dramatically increased performance at no security cost.
And more is coming in the 0.9 branch. It is planned to feature:
Encryption of communications between nufw and nuauth. This is very soon.
Support for several Nufw gateways on nuauth
Application match support.
Full IPv6 support
The status of this release is alpha. It seems to be stable, but lots of things will be done and thus the code is subject to evolution and unstability.
