Astaro Security Linux provides firewalling, VPNs, spam, virus, and surf protection in an all-in-one network security gateway. Its features include stateful packet inspection, deep packet filtering, application-level intrusion detection, content filtering, virus detection for email traffic (SMTP and POP3) and Web traffic (HTTP), whitelists and blacklists, IPSec and PPTP VPN tunneling, spam blocking, logging, and reporting.
The software is built on an embedded, especially hardened Linux distribution. The WebAdmin tool and Up2Date service make it easy to install, manage and update all six security applications. This version includes virus protection for HTTP, intrusion protection, L2PT VPN-support, ISP-uplink failover, spam protection for SMTP and POP3, SMP support, and stateful failover functionality in high availability installations.
Many small improvements were also made. This release improves speed, downloads, and stability of the HTTP Proxy and the QoS packet classification. It includes fixes for accounting not working properly, traffic on VLAN interfaces not being reported, SMTP messages, the spam header showing up in the email body, pattern Up2date not possible even with a valid license, IPS license being improperly checked, the POP3 proxy blocking all messages, the SNMP daemon consuming too much CPU, the authentication page possibly being blank, and PPTP assigning the same IP address to multiple clients.
