Yes. # netstat -nra | wc -l 32468 # A couple of examples: 2002:41a:1e23::41a:1e23 2002:c058:6301::1741 UHW3 stf0 2002:41a:1eaa::41a:1eaa 2002:c058:6301::1741 UHW3 stf0 2002:41a:6b0e::41a:6b0e 2002:c058:6301::1741 UHW3 stf0 2002:41a:6f4b::41a:6f4b 2002:c058:6301::1741 UHW3 stf0 2002:41a:70f5::41a:70f5 2002:c058:6301::1741 UHW3 stf0 1433 2002:41a:7411::41a:7411 2002:c058:6301::1741 UHW3 stf0 2002:41a:8e81::41a:8e81 2002:c058:6301::1741 UHW3 stf0 That's basically about all the 2002:xxx addresses which have been relayed through. I'd suspect the number is maxed and garbage-collected around 2^15 though, because the box is relaying w/ much many more addresses than that. I guess this provides a hint at a very probable source of leakage. > 2. if you specify the "link2" flag on the stf interface, what if you > do not specify it?

This would be a bit difficult, so I'd like to avoid it if possible. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks. Security. -- George R.R.
