Open Source C Firewall Software - Page 3

No port forwarding, DMZ, and others are required, Trate allows other applications - almost all applications(VNC,WinSCP,BitTorrent,Filezilla,ssh,Web/Ftp etc) - to auto-create dynamic connections between two peers behind two separate NATs and firewalls.

The doorman guards the door of a server, manipulating firewall rules to admit only recognized parties. Allows Silent Running - a server with all ports CLOSED. Linux-BSD-OSX server & client; C source & docs + Windows client binary. GPL.

Snort_inline is a modified version of Snort. It accepts packets from iptables, instead of libpcap. It uses new rule types to tell iptables if the packet should be dropped or allowed to pass based on the Snort rules.

A windows c++ program to test various libraries on various routers to forward ports on routers.

TuxGuardian is an application-based firewall with a graphical interface. It's main task is to control and forbid transmission & reception of data by unauthorized applications; it can be thought as the Linux equivalent to apps such as ZoneAlarm and Kerio

The use of NAT devices all over the Internet has made peer-to-peer exchanges unreliable. The rise of IPv6 should repair this, but it will still not be reliable until all peers have implemented IPv6. Such IPv6 implementation could be arranged on the fly with a tunnel mechanism that does not rely on router co-operation or manual configuration. This specification details such a method of embedding IPv6 into UDP and IPv4. It employs embedded Router Solicitation to configure the tunnel's public IPv6 address, and Neighbor Discovery to try to find the remote peer over more efficient IPv4 routes.

The ADSL optimizer is an accurate packet scheduling solution for ADSL connections, based on Linux and HTB. The solution guarantees low latency while maintaining full utilization of both upstream and downstream, without wasting link capacity.

ADSL4Linux is a program to connect your Linux box via ADSL to the internet in as few steps as possible. This is all done in the easiest possible way. Also contains two Firewalls (ipchains and iptables).

AGT is a powerful console frontend to iptables, supporting nearly all of the iptables extensions. All options can be specified in a configuration file with similar syntax to 'ipf' and 'ipfw'.

ReAIM is an AOL Instant Messenger Proxy for iptables-based firewalls. It allows direct connections to be made to hosts behind an address-translating firewall. MSN and Windows Messenger are also supported.

Amber - a "grey list" for Qmail. Amber sits in the tcpserver chain, not accepting or rejecting mail but deferring connections from new IP addresses for some time (default five minutes) before it starts accepting mail from them.

Anoubis is a Security Suite which implements a secured environment for applications. The core of the suite is an Application Firewall alongside with a Sandbox. Mechanisms to assure the authenticity of files, directories and applications are provided.

The goal of the project is to build a framework to allow Astaro firewall users to install optional software packages on their firewalls. (Astaro is a Linux-based firewall available from www.astaro.com.) Such a framework includes a package-management syst

Linux Authentication Gateway which allows to make dynamic firewall rules based on usernames.

Bandwidth Management Tools is a total bandwidth management solution for Linux and can be used for firewalling, traffic graphing, and shaping. It is not based on any currently-available bandwidth management software some ver advanced features.

BrFW is an application firewall, the user will specify what programs are able to open sockets (RAW / IP / UDP / TCP...). BrFW alerts when another program try to access the network.

Bruteblock allows system administrators to block various bruteforce attacks on UNIX services. The program analyzes system logs and adds attacker's IP into IPFW table effectively blocking them. Addresses are removed from the table after expiration period

The program implements the CIDR merging with whitelisting (network exclusion). Output will be summarized to be as small as possible. The program has been widely used for blacklist merge and optimization.

A package for encrypted IP over UDP tunneling. Can be used to build any range of VPN solutions. (Linux version)

Implements a Windows NT VPN peer to Olaf Titz's CIPE VPN for Linux NOTE: The distribution must be downloaded from the home page

Provide secure, quality, user-friendly and fail-proof access to internet manager for IPTABLES-DENY-ALL-based Linux configuration of firewall, including traffic and time accounting, logging, auto-disconnection. Software for i-net clubs and caffee admins

CRYPT extension for Netfilter/Iptables allows you to create an encrypted communication using stream and block ciphers. It also authenticates the packets.

Campagnol is a decentralized VPN over UDP tunneling. It uses UDP hole punching to open connections through NAT/firewall and OpenSSL's DTLSv1 implementation for mutual authentication and encryption.

CartoReso intends to facilitate enterprise computer network mapping.

The library implements generic content inspection protocol API compatible with Sendmail Milter, thus allowing various applications and proxies to use Milter-compatible filters without running sendmail itself. It is here to replace Checkpoint\'s OPSEC/CV
