Hello,
there are two options to get Ping for IPv6 to work:
- IPv6 / ICMP / Echo Request
- IPv6 / IPV6-ICMP / Echo service request
What is "Echo service request"? - I got no results searching for that exact phrase.
Thanx for any hint.
ICMP / Echo Request is for IPv4.
Side note: I've seen a bug in OPNsense when editing rules that sometimes the "ICMP / Echo Request" values stick around when changing the IP version from IPv4 to IPv6. You get an error when trying to save the rule in that case and then you have to just change them to "IPV6-ICMP / Echo service request" manually and re-save.
