The Centre for Advanced Internet Architectures (CAIA
http://caia.swin.edu.au) is proud to announce the release of alias_sctp
version 0.2, an SCTP NAT patch to FreeBSD 8.x.
Alias_sctp provides SCTP NAT functionality to the ipfw/ipfw_nat/libalias
suite. Alias_sctp version 0.2 is a fully functional NAT for SCTP. It is
part of the CAIA SONATA project (http://caia.swin.edu.au/urp/sonata).
The code has been intentionally kept as separate as possible from the
base modules to aid testing and debugging, and make it easier to port to
other systems.
We welcome and value feedback and comments.
Please forward feedback to [EMAIL PROTECTED] and [EMAIL PROTECTED]

Features of alias_sctp version 0.2:
- Support for global multi-homing
- Support for multi-homed privately addressed hosts using ASCONF
modifications from the Internet Draft (R. Stewart and M. Tuexen,
"Stream control transmission protocol (SCTP) network address
translation", draft-stewart-behave-sctpnat-04, Jul. 2008)
- Support for forwarding of T-flagged packets
- Generation and delivery of AbortM/ErrorM packets upon detection of
NAT collisions
- Per-port forwarding rules
- Dynamic configuration (via sysctl interface) of:
o Logging and statistic gathering
o Timer management
o Hash Table sizes
o Global address storage and other processing limits
- Configuration via use of the "ipfw nat ... config"
- Stateful SCTP association management.
This project has been made possible in part by a grant from the Cisco
University Research Program Fund at Community Foundation Silicon Valley.
