Bug 43662

Summary:	Cannot use DNS forwarding service of Draytek Vigor 2600 ADSL router

Description Rik Hemsley 2002-10-04 18:20:02 UTC

Router does DNS forwarding, which works just fine for other machines
and other OSes, but FreeBSD doesn't seem to work with it. strace shows
it sending a DNS lookup to the router, then waiting about 10s and repeating. After about 2 minutes, it seems to manage the lookup and
connects.

How-To-Repeat: Use Draytek Vigor 2600 ADSL router's DNS forwarding service.

What does a tcpdump of the session show?  What exactly is the query that
the FreeBSD box sends to the router?  Does it reply at all?  In short,
show us the full output of the following command, started before the DNS
query session:

tcpdump -nli xl0 port 53

..substituting the name of your network interface for xl0, of course :)

G'luck,
Peter

I am jealous of the first word in this sentence.

Please close this bug. I have found out that the DNS forwarding service of this
router is horribly broken. Lots of other people on non-Windows OSes have had
similar problems.

Sorry for the inconvenience.
