It can be tunneled (inefficiently) over UDP, but it isn't implemented on top of UDP. SCTP is protocol 132; UDP is protocol 17. See http://www3.ietf.org/proceedings/00jul/I-D/sigtran-sctptunnel-00.txt Or see RFC 2960, or check your /etc/protocols. Userspace implementations exist, but they typically require raw IP access, and you'd still need ipsec as described in the referenced post. yrs, -- Nick Mathewson
