I have read and followed the "Reporting Problems" section on the Contact page and am providing the following details for this report based on the list of items stated there: Handle: JK22-SIXXS On Debian Lenny (stable), dnsutils 1:9.5.1.dfsg.P1-1 root@hansu:~# host maps.google.com 2001:14b8:0:3007::6 ;; reply from unexpected source: 2001:14b8:100:202::1#53, expected 2001:14b8:0:3007::6#53 ;; reply from unexpected source: 2001:14b8:100:202::1#53, expected 2001:14b8:0:3007::6#53 root@hansu:~# host 2001:14b8:100:202::1 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.2.0.2.0.0.0.1.0.8.b.4.1.1.0.0.2.ip6.arpa domain name pointer gw-515.hel-01.fi.sixxs.net. The error is quite clear. The result is that I can't use the name nscache.eu.sixxs.net since at least some of the servers reply from the tunnel endpoint address instead of the DNS server address I queried from. Is it possible to reconfigure DNS servers on tunnel endpoints (fihel01 at least) to reply from the configured address?
