Siproxd is a SIP application layer proxy for SIP-based softphones hidden behind an IP masquerading (NAT) firewall. It includes an RTP data stream proxy for incoming and outgoing audio and video data. Multiple local UAs (SIP phones) can be simultaneously masqueraded. All configuration is done via one simple ASCII text file. Its main purpose is to perform NAT traversal for SIP and the RTP traffic.

The following modules are available: accounting, digest authentication, CPL scripts, ENUM support, instant messaging, MySQL support, PostgreSQL support, a presence agent, Radius authentication and accounting, Diameter authentication, record routing, an SMS gateway, a Jabber gateway, NAT traversal support transaction module, a registrar, and user location.
StreamGate is a proxy server for MP3 streams written in Java. With StreamGate, you can define multiple streams that will be streamed to the clients in your network. The advantage is that you'll save lots of bandwidth when you have several clients that listen to the same streams. StreamGate is working "on demand" and uses no bandwidth when no clients are connected.
NatACL is a Linux firewall group policy controller for intranets and Internet. Using a internal DHCP server, it can force users to use a DHCP client, and you can block static IPs. It will bind an IP to a MAC address and enforce this usage. You can control groups that can see each other with intranet policies, or control who has access to the Internet. It also has an option to force users to authenticate themselves over the Web before accessing the Internet.

Charles is a Web debugging tool, HTTP monitor, and reverse HTTP proxy for Web developers that includes plain text debugging of HTTPS/SSL. It is built in Java Swing, and runs on all Java platforms. It is an HTTP proxy server that displays requests and responses, complete with HTTP headers. This enables the developer to examine the exact content of HTTP exchanges, including cookies, caching, and redirects. It can also throttle your connection in order to simulate modem conditions. It is a valuable tool for all Web developers and is especially useful for debugging XML RCP, SOAP, Web services, AJAX/XMLHTTP, and Macromedia Flash client-server traffic including AMF, AMF 3, LoadVars, and XML Sockets.
fk_html is a standard filter for incoming mail. It runs on your local machine as a fake POP3 server that redirects your mail client connections to your real POP3 server. Doing that it can scan, filter, and convert your incoming emails and is totally independent from your mail client type or version It provides multiple account settings, conversion from HTML mail to plaintext mail, removal of scripts from HTML mail and attachments, address filtering based on blocklist and allowlist, the ability to apply different policies to different accounts, and SSL support (also for non-secure clients, in which case only the loopback connection is not encrypted).
