zdravim, neviem presne kedy sa ten log zacal objavovat, ale pri nasadeni DNS serveru (pihole) som si ho vsimol. Su to dva typy logu:
input: in:host_vlan out:(unknown 0), src-mac (gateway od mojho ISP - NAT 1:1), proto UDP, 0.0.0.0:68->255.255.255.255:67, len 328
input: in:host_vlan out:(unknown 0), src-mac (klienty hostitelskej VLAN), proto UDP, (IP klienta):68->(IP mojho Mikrotiku pre hosti):67, len 328
Siet tvoria dve VLANy jedna sukromna v ktorej su vsetky zriadenia a druha pre hosti Na MT su spustene aj dva DHCP servery (pre kazdu VLANu jeden). DHCP servery funguju, ale ten hostovsky opakovane hadze vyssie uvedeny log.
Donedavna som na MT pouzival aj DNS server, ale presiel som na pihole, takze som z hostovskej VLANy otvoril port 53 na pihole v sukromnej VLAN (nemyslim ze to suvisi).
Tento filter pouzivam uz dlho a este som nezaznamenal log ohladom portu 67, 68 (az teraz) a v poslednej dobe som nemenil ani pravidla logovania. Vie mi niekto povedat co to moze znamenat? Je niekde problem?
