Firewall - ICMPv6 matches not working as expected on 1.3.0
Closed, ResolvedPublicBUG
Actions

Description

On VyOS 1.3.0, this rules doesn't generate correct firewall rules:

# Firewall rules
[email protected]# run show config comm | grep fire
set firewall ipv6-name FOO-v6 rule 10 action 'drop'
set firewall ipv6-name FOO-v6 rule 10 icmpv6 type 'echo-request'
set firewall ipv6-name FOO-v6 rule 10 protocol 'icmp'
set firewall ipv6-name FOO-v6 rule 20 action 'accept'
set firewall ipv6-name FOO-v6 rule 20 icmpv6 type 'parameter-problem'
set firewall ipv6-name FOO-v6 rule 20 protocol 'icmp'
[edit]

# nft tables
[email protected]# sudo nft list chain ip6 filter FOO-v6
table ip6 filter {
	chain FOO-v6 {
		meta l4proto icmp counter packets 0 bytes 0 drop comment "FOO-v6-10"
		meta l4proto icmp counter packets 0 bytes 0 return comment "FOO-v6-20"
		counter packets 0 bytes 0 drop comment "FOO-v6-10000 default-action drop"
	}
}
[edit]

As you can see, both rules are equals (except action that is different), and no "type" are inserted in rules.
