I've had this many many times, the DSL service is more than 12 years active and this trick went into production on the first day it came in service ;-) > > To solve this, multiple times with various different locations, I ended > > up setting up local resolving DNS server, recently this became Unbound, > > on the gateway OpenBSD system, and it does resolution directly querying > > root DNS servers.

If the ISP you're going through does capture all outgoing DNS traffic and force redirects it through their name serverice, another go at it is to optionally tunnel out (ssh, or anything else) and use DNS service via the tunnelled connection. Either set Unbound, or another recursive resolver there and use it for your resolver, or simply pass your DNS traffic for your own resolving name server through the tunnel. The Unbound DNS resolver is in base, let me know if you need any tech details with this in direct message and I'll add more specific details. > Thanks, > Chris
