ICMPv6 filtering on type / code

RouterOS Beginner Basics

Hi there!,

Is it posible to add IPv6 / ICMPv6 firewall rules specific to an ICMPv6 type / code? I don’t see any specific option for this in winbox, and the ICMP Options shown seem to be for ICMP(v4).
Can you specify them in the CLI, and if yes, what is supported and what is the commandline and supported types/codes?

I looked through http://wiki.mikrotik.com/wiki/Manual:IPv6/Firewall , but I did not found (m)any useful information there.

For info: i’m using ROS 5.21 on a 750GL.

Thanks in advance,
Mick

Yes it is possible

[admin@MikroTik] /ipv6 firewall filter> add icmp-options=

IcmpOptions ::= [!]Type[:Code]
Type ::= 0..255 (integer number)
Code ::= Start[-End]
Start,End ::= 0..255

the same parameter configuration is available in winbox.

Thanks for making that clear!
Don’t know why I did not just type in the type / code values. I guess i had an off-day. :blush:
