| Summary | 0003213: udp address validation denied due to address mismatch, despite address matching | ||||
| Description | I have this in my logs: Dec 13 19:10:56-337164 nat-2175 WARNING Asked to validate one of my addresses and validation failed! Dec 13 19:10:56-361668 transport-2175 ERROR Address `udp.0.217.92.15.146:2086' is not one of my addresses, not confirming PING However, 217.92.15.146 IS the correct IP+port (and while NATed, the NAT is punched, so this external IP should be considered correct). | ||||

One possible explanation (especially given my setup) is that nat.c::resolve_dns periodically (!) resolves the DNS name given for the external IP address (i.e. for DYNDNS). However, when it does so, it FIRST removes the existing mappings (remove_from_address_list_by_source, LAL_EXTERNAL_IP) and THEN does the DNS lookup which (eventually) adds the new mappings. In the meantime, there is thus a time window where PINGs would go unanswered. We could fix this by removing the 'old' mappings only after the new mappings have been added. |

Should be fixed in SVN 31377. |
