Hello all,
I'm facing a weird behavior using IPv6 connection mark on RouterOS v7.6 Stable. I'm setting a new connection mark to ICMP (protocol ICMPv6) and DNS (UDP port 53) connections, then I mark packets to QoS simple queue.
I have noticed some connection UDP 443, but there is no rule in mangle that match this protocol/port to me marked as "ICMP+DNS_conn". As shown below, I have only 2 rules to mark this connections.
There are a 3 attachments to illustrate this.
Connection marks in mangle:
Connections marked correctly:
Connection that should not be marked:
Can someone please point me a direction?
