Maybe we should recommend some outbound firewalling for such known nuisances?
To reduce traffic, drop neighbor discovery and smb as well as MikroTik
Neighbor Discovery Protocol on tunl0 (optional, but a good idea):
iptables -A OUTPUT -o tunl0 -p udp --dport 10001 -j DROP
iptables -A OUTPUT -o tunl0 -p udp --dport 137:139 -j DROP
iptables -A OUTPUT -o tunl0 -p udp --dport 5678 -j DROP
