I'm looking for a way to create an iptables mangling rule that will allow traffic from a local ip and port to be redirected to an external ip address. I realize this is normally not a good idea, but a proprietary piece of software we are using requires connections to be made from non-internal IP addresses on the LAN.

Linux IPTables Mangling Rule

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
