FTP Protocol extensions permit the use of a special "EPRT" command. This extension provides a protocol neutral alternative to the IPv4-only PORT command. When supported it enables active FTP data channels over IPv6 and efficient NAT handling. Turning this OFF will prevent EPRT being attempted and will skip straight to using PORT for IPv4 servers. Some devices are known to not handle this extension correctly and may result in crashes. Devices which support EPRT enough to fail cleanly will result in Squid attempting PORT anyway. This directive should only be disabled when EPRT results in device failures. WARNING: Doing so will convert Squid back to the old behavior with all the related problems with external NAT devices/layers and IPv4-only FTP. |
