This fixed the directly triggerable ping-pong between the two servers. Now
I still see these requests sometimes:
Nov 11 10:30:19 theq dnsmasq: query[PTR]
db._dns-sd._udp.0.64.168.192.in- addr.arpa from 10.117.15.254
Nov 11 10:30:19 theq dnsmasq: forwarded
db._dns-sd._udp.0.64.168.192.in-a ddr.arpa to 10.117.15.254

starting again dnsmasq on 192.168.64.254, everything is back to normal
