Hi, I do not know how to summarize my problem in a short sentence, sorry for the meaningless title. I cannot access *.dropbox.com here. But lucky I have a ipv6 tunnel working. So I have an idea here: redirect all queries to *.dropbox.com to *.dropbox.com.sixxs.org to make dropbox tools working. So I installed bind9 and set it as local DNS service. But then I missed. CNAME does not seem work. Any idea? Thanks. -- 竹密岂妨流水过 山高哪阻野云飞
