[-- Attachment #1 --] I have setup 3 nodes on a fresh Freebsd 13.1-RELEASE-p1. They have the same gateway and IPS are in same /64. All 3 nodes are on the same switch (mikrotik) and same vlan untagged. I can ping them from an external machine through the router/gateway but the nodes can't ping each others. When I run `ndp-a` it only return the gateway and the node ipv6 (+ their libks) but not the ips of the other nodes. Previously these nodes wee under linux and were able to ping each others. What could be the issue? What do I need to check? Configuration is pretty straightforward: ``` hostname="node1.domain.tld" keymap="fr.macbook.kbd" ifconfig_ql0="" ifconfig_ql0_ipv6="inet6 <PREFIX>::11/64" ipv6_defaultrouter="<PREFIX>::1" sshd_enable="YES" ntpd_enable="YES" # Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable dumpdev="AUTO" zfs_enable="YES" ``` Others machines are `<PREFIX>::12`, `<PREFIX>::13`Sent from Proton Mail for iOS Benoît [-- Attachment #2 --] <html><head></head><body> <div><br></div><span>I have setup 3 nodes on a fresh Freebsd 13.1-RELEASE-p1.
