Jateway is a general purpose TCP/IP connection proxy
Jateway is a general purpose TCP/IP connection proxy.
Jateway accepts connections on arbitrary ports (like 80 or 443) and specific host:port combinations (like WANIP1:443 and WANIP2:443) for multi-interface systems
Supports single TCP connections (like MySQL), and multi-TCP connections like HTTP and HTTPS, and fowards them to arbitrary host/port combinations.
iplist is a list based packet handler which uses the netfilter netlink-queue library (kernel 2.6.14 or later). It filters by IP-address and is optimized for thousands of IP-address ranges.
Server/client suite which provides per-user access control/firewall/QOS. Robust and high speed implementation is secure against MAC/IP spoofing, and can scale to large networks with many clients. Options for additional monitoring and captive portal.
A simple port-relaying program written in Java; sits on specified ports for either TCP or UDP, re-sends packets to the given IP. Doesn't forward packets, actually receives and re-sends them. Could be handy to learn Java Sockets/networking. Public Domain.
JavaTunnel is a java, free, tunneling program.
It can function in two ways: 1 It can open TCP/IP tunnel between two computers, using HTTP as a transport(not yet). 2 It can open a connection directly, witht he help of a SSL-HTTP proxy(avaible now).
TCP-Switch currently allows sharing one port for four protocols (SSH, HTTP, HTTPS, passive FTP).
Each protocol can be forwarded (tunnel) to a different <host:port>.
Future releases will allow much more controll, e.g. client IP/port, and other protocols
Java Port Mapping between 2 hosts. Put up a server on your local network and share it with the outside network in a secure way. A \"server proxy\" network tool. Share one IP with multiple servers.
