Astaro Security Gateway (formerly Astaro Security Linux) is an all-in-one network security gateway that includes a firewall, intrusion protection, antivirus, spam protection, URL filtering, and a VPN gateway. Features include a modern packet filter, intrusion detection and prevention, portscan detection, application control, content filtering, virus detection for email and Web traffic, profile handling, L2TP, IPSec, SSL, and PPTP VPN tunneling, spam blocking, proxies for HTTPS, HTTP, FTP, POP3, SMTP, DNS, VoIP, SOCKS, and Ident, logging, and reporting. It supports Ethernet, VLAN, PPP, PPPoE, PPPoA, Cable Modem, IPv6, QoS, Link Aggregation, and WAN-Uplink-Load balancing in routing, and bridge mode. The WebAdmin GUI, Install Wizard, Change Tracking, Printable Configuration, and Up2Date service make it easy to install, manage, and maintain.
SSA SQL sniffer is an TCP SQL stream adapter that allows you to capture, adapt, and forward TCP streams with SQL statements sent through the network. It allows you to adapt your software database repository to a different database. It has an Oracle/PostgreSQL driver to perform conversion from an Oracle TCP SQL stream to PostGreSQL. It supports SELECT, INSERT, UPDATE, and DELETE.
FastFwD is a small daemon that allows users to set up port forwarding from a source IP address and port number to a target IP address and port number easily without the need to deal with complicated ipchains/iptables-rules. FastFwD offers a fault-proof possibility for port forwarding between two networks or IP addresses and additionally gives the possibility to password-protect this connection. FastFwD has been tested for Linux and QNX and should compile and work with all POSIX-based systems.
SquidTL allows proxy administrators to manage proxy users: define how much time users can spend on a specific Web site, block sites, limit total time users can spend on the Web daily, and watch users' activity. For example, you can limit the use of Facebook or other social networks with per-user rules or IP. It has a small memory footprint and very fast execution. Management can be done with a smart Web-based administration GUI.
pwnat, pronounced "poe-nat", is a tool that allows any number of clients behind NAT gateways to communicate with a server behind a separate NAT with no port forwarding and no DMZ setup on any routers in order to directly communicate with each other. The server does not need to know anything about the clients trying to connect, nor does it need to communicate with any other hosts in order to initiate the communication. Simply put, this is a proxy server that works behind a NAT, even when the client is behind a NAT. There is no middle man, no proxy, no third party, no UPnP required, no spoofing, and no DNS tricks. More importantly, the client can then connect to any host or port on any remote host or to a fixed host and port decided by the server.
The Apache Traffic Server (TS or ATS) is a modular, high-performance reverse proxy server, generally comparable to Squid. It was created by Inktomi, and distributed as a commercial product called the Inktomi Traffic Server, before Inktomi was acquired by Yahoo!. Traffic Server has been actively used inside of Yahoo for over 4 years, serving billions of requests every day. As of fall 2009, Traffic Server is an Open Source project, and in April 2010 the Apache Traffic Server was promoted to a top-level project of the ASF.
