The Portable Transport Relay Translator Daemon (pTRTd) is used to translate TCP sessions between IPv4 and IPv6, allowing hosts with only IPv6 connectivity to access the IPv4 Internet. This implementation of RFC 3142 uses a self-contained IPv6 stack to allow for full portability to any Unix operating system.

Recent releases


Release Notes: UDP translation is now supported. Neighbor Discovery reliability has also been improved.


Release Notes: Linux 2.2.x is now supported. ptrtd was changed to attach to the host using an Ethernet-style "tap" device rather than an IP-style "tun" device. Also, several bugs were fixed that could have caused crashes in 0.5.0.


Release Notes: This alpha-test release of pTRTd should not be run outside of an isolated IPv6 network as it probably contains security holes.
