I started a Wiki page for IPv6 Troubleshooting (just a start) To be complete, I am trying to give examples for Linux/*BSD and Windows IPv6 setups. I just have some basics on the page right now including ping/tracert/nslookup/mtu. https://www.sixxs.net/wiki/IPv6_Troubleshooting Feel free to add your own information to the page, or give examples. When the page gets a bit more content, I will add some links to the page from other parts of the Wiki and the contents page. Thanks in advance, and apologies if this information has already been hashed through or listed elsewhere. --Dave
