Kernel cannot forward src
-
pfSense 2.4.4 and previous versions on ESXi home lab.
Configured DualstackWAN IPv4+IPv6 via Tunnelbroker with MultiWAN in failover mode (no balancing).
In general system log I see many errors:
Kernel - cannot forward src fe80:3::1111:2222:3333:, dst 2a02:1111:2222::3333:4444, nxt 6, rcvif vmx2, outif gif1VMX2 is LAN and GIF1 is tunnel brocker interface.
Point in that src and destination from one error to another are changing and Main problem:
I don't have IPs fe80:3::1111:2222:3333 in LAN for every case, but I have IPs fe80::1111:2222:3333 for each of them, how it can bee? pfSense add :3:: after fe80 don't get why. -
Some client is incorrectly attempting to send traffic from a link-local address to a remote destination. You can't do that, so it gets dropped and logged.
fe80::/10 link local traffic can't leave its segment.
pfSense may not list that address since it's only on the local segment. It's an address that a device would assign to itself. The
:3:would not come from pfSense, that may be a different interface on the client. -
Ok, thank you, sorry for duplicated theme.
About :3:: - it really not existing IP at all, but real if remove this part. I sure, because have ntopng installed and have configured monitoring for long time storing. For me this strange situation.
P.S. This clients is Win10.
