What is your need for NAT64? If you just want to look at IPv4 websites (in the case of disabling IPv4 and then use a HTTP proxy...) Other solution that scales and works: SOCKS, v5 of course due to passing of hostnames and thus the SOCKS server doing the lookups. > * Squid 3.0; Squid 3.1 supports IPv6, but is still not in Sid; Squid developers are then also very lazy and slow wrt IPv6. http://cacheboy.net/ is probably the answer to that; and of course Apache2 works fine too. > * `flow-tools' and `fprobe-ulog'; (use `nfdump' and `softflowd' > instead? oh well, `nfdump' depends on... `ttf-dejavu'! thanks > to the `librrd4' dependency); If you require gratuit NetFlow something NFSen/NFdump is the best you can get, if you have a wad of cash then there are other options ;). You need NFv9/IPFIX though for actually supporting IPv6. There are various probes that support IPv6, google around for IPFIX helps as generally they then also have IPv6 support. > * VoIP -- apparently, neither Ekiga nor Linphone support IPv6; > any suggestions?

FreeSWITCH, which is not in Debian yet, does IPv6, SCTP, Jingle, ZRTP (if you have the SDK) etc all out of the box (fetch from svn & dpkg-buildpackage -b, install debian packages, presto) The patches for both come from the same people, thus I guess there is a problem at * which is blocking it all, which is a shame (and caused me to switch to freeswitch, which does have all the good working features) > * (still have to investigate whether my D-Link WiFi access point > passes IPv6 or not; but wait, that isn't related to either > Debian or my home LAN.) It is if you run Debian on the thing ;) [as a side-note: generally OpenWRT does a perfect job as an IPv6 gateway] Greets, Jeroen
