Hi, I have the same problem.
It sounds to me like this this [1] upstream commit (included in 2.88) should fix the issue. (Please note that I lack experience in building packages so can't verify this i.e. I tried neither the patch nor 2.88) Regards, Thomas[1] https://github.com/ldir-EDB0/dnsmasq/commit/930428fb970f4991e5c2933fd5a5d2504c18a551
