I use unbound via opnsense and am hitting an issue.</div><div><br></div><div>I have successfully set up a forward-zone for my `ts.net` domain to tailscale’s DNS and it works great. I want to do the same for reverse lookups. All tailscale addresses are in the 100.0.0.0/8 range. So I added the following to my config (via the GUI, but verified in the config file):</div><div><br></div><div>—</div><div><div># Forward zones</div><div>forward-zone:</div><div> name: "100.in-addr.arpa"</div><div> forward-addr: 100.100.100.100</div></div><div>—</div><div><br></div><div>This does not seem to work. Any request to look up an address (like 100.94.184.34) returns:</div><div><br></div><div>Host 34.184.94.100.in-addr.arpa not found: 3(NXDOMAIN)</div><div><br></div><div>If I do the /16 subdomain like:</div><div><br></div><div>—</div><div><div># Forward zones</div><div>forward-zone:</div><div> name: "94.100.in-addr.arpa"</div><div> forward-addr: 100.100.100.100</div></div><div>—</div><div><br></div><div>It works just fine.</div><div><br></div><div>Am I not allowed to forward an /8 in-addr.arpa?</div><div><br></div><div>Thanks in advance!</div><div><br></div><div><div dir="ltr"><div><span style="background-color: rgba(255, 255, 255, 0);">-Jeremy</span></div><div><span style="background-color: rgba(255, 255, 255, 0);"><br class="webkit-block-placeholder"></span></div><span style="background-color: rgba(255, 255, 255, 0);">----</span><div><span style="background-color: rgba(255, 255, 255, 0);">Jeremy Beker - <a href="mailto:gothmog@confusticate.com">gothmog@confusticate.com</a></span></div><div><a href="http://www.confusticate.com/" style="caret-color: rgb(0, 0, 0); background-color: rgba(255, 255, 255, 0);"><font color="#000000">http://www.confusticate.com</font></a></div><div><span style="background-color: rgba(255, 255, 255, 0);">Condensing fact from the vapor of nuance.</span></div></div></div></body></html>
