IP Masquerade HOWTO project is a document describing how to set up IP Masq (NAT) for Linux systems.
It contains instructions on understanding, configuring, and troubleshooting NAT or Network Address Translation for Linux.
It covers topics such as IPTABLES, PORTFW, IPCHAINS, IPFWADM, stronger packet firewalls, multiple network segments, and configuring many client operating systems. It also has an extensive FAQ and troubleshooting section.
What's New in This Release:
Fix a bug where the PORTFW example rule in section 6.7 was incorrect. Updated the IPTABLES PORTFW section to include state tracking for the pre-routing rule, added a cross-reference to the PORTFW FAQ entry, and reduced some duplicate PORTFW examples in different chapters of the HOWTO. Thanks to Thomas Zajic for bringing this to my attention.
Updated the dynamic IP FAQ section to give complete examples on how to re-run the rc.firewall-* scripts for various different DHCP clients
Updated the HOWTO to be very clear on loading the various rc.firewall-* rulesets (there are 6 of them in this HOWTO both simple and stronger versions for IPTABLES, IPCHAINS, and IPFWADM) files vs. loading a generic rc.firewall file. I also updated the troubleshooting section to reflect this possibly confusing point.
Updated the Multiple NAT situation to include ProxyARP solutions
Clarified the section for IPMASQ on multiple internal LAN segments
