I 'm also able to visit the site, http://www.bluestop.org/sctpDrv, and download files. :-)

BTW, are there anyone who knows the solution that enables sctp packets to be forwarded over "Netsh command-line tools for NAT" on Windows XP?
Actually, I'd like a Windows machine to be a NAT entity for other machines in a private network. There could exist two kinds of ways to realize that --"Internet Connection Sharing" and "netsh routing ip nat". Although http, icmp, ftp traffic can get to the global network through the NAT without any issues using both above ways, sctp traffic seems to be blocked/filtered at the NAT. If anyone knows other solutions, please let me know.
