Zeroshell 2.0.RC2

Zeroshell 2.0.RC2 improves the support for the load balancing and fault tolerance of multiple connections to the Internet. Particularly, this release allows to keep in Standby PPPoE (xDSL) and UMTS/HSDPA connections, activating the PPP protocol only in the event of absence of connectivity from other accesses. These connections are again placed in standby mode when connectivity is recovered from the default accesses. Improved the Failover mechanism with check in Layer 2 as well as with ICMP. Updated the VPN Bonding for bandwidth aggregation and failover of the LAN-to-LAN connections. Fixed several bugs in the system. In particular, it has been solved a problem that caused the freezing of the Captive Portal under high load.
