Hi,
since last update i noticed on my smokepings that i have higer pings and a litle packetloose.
1st i thought itsmy internet but it seems its the new pihole update flooding my network with ras.
ive also lost the ipv6 gateway from time to time.
when i do
tcpdump -vvvv -ttt -i eth0 icmp6 and 'ip6[40] = 134' on a linux client i get 100 of packets per second constantly.
00:00:00.001975 IP6 (class 0xc0, flowlabel 0xebe11, hlim 255, next-header ICMPv6 (58) payload length: 112) rpi2 > ip6-allnodes: [icmp6 sum ok] ICMP6, router advertisement, length 112

the pihole.logs shows
dnsmasq-dhcp[20577]: RTR-ADVERT(eth0) 2a02:XXX:XXX
329 in 1 second
any1 can confirm this ?
ive stopped it now by disabling
#dhcp-range=2a02:XXX::,ra-stateless,ra-names
disabling the option enable-ra didnt worked.
Changing the ra-param to like 60seconds also dont help it still spams
The defualt config from pi.hole works
#quiet-dhcp6
#enable-ra
dhcp-option=option6:dns-server,[::]
dhcp-range=::100,::1ff,constructor:eth0,ra-names,slaac,24h
ra-param=*,0,0
no flodding but mine floods the whole network
#dhcp-range=2a02:XXX:XXX:XXX::,ra-stateless,ra-names
