That's your link-local gateway IP, it exists on every interface that obtains its IP via PD. It's common to use that as a gateway IP in that case. It also provides an easy IP to use to hit the GUI. > Indeed workstations on the LAN capture fe80::1:1 for their default gateway > and even pinging that IP from a workstation doesn't work: > > ping6 fe80::1:1 > PING6(56=40+8+8 bytes) fe80::aa20:66ff:fe21:7c8e%en2 --> fe80::1:1 > ping6: sendmsg: No route to host You need an interface scope when pinging link local. For instance on a Linux host whose connected NIC is wlan0, this is pinging the gateway IP on a PD-configured interface. $ ping6 fe80::1:1%wlan0 PING fe80::1:1%wlan0(fe80::1:1) 56 data bytes 64 bytes from fe80::1:1: icmp_seq=1 ttl=64 time=3.01 ms 64 bytes from fe80::1:1: icmp_seq=2 ttl=64 time=3.20 ms 64 bytes from fe80::1:1: icmp_seq=3 ttl=64 time=3.49 ms ^C --- fe80::1:1%wlan0 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2002ms rtt min/avg/max/mdev = 3.010/3.235/3.493/0.209 ms $ ip -6 neighbor fe80::1:1 dev wlan0 lladdr 00:08:a2:09:3b:b4 router REACHABLE Or on a Mac where en0 is the interface. $ ping6 fe80::1:1%en0 PING6(56=40+8+8 bytes) fe80::426c:8fff:fe2c:d08%en0 --> fe80::1:1%en0 16 bytes from fe80::1:1%en0, icmp_seq=0 hlim=64 time=0.225 ms 16 bytes from fe80::1:1%en0, icmp_seq=1 hlim=64 time=0.252 ms ^C --- fe80::1:1%en0 ping6 statistics --- 2 packets transmitted, 2 packets received, 0.0% packet loss round-trip min/avg/max/std-dev = 0.225/0.238/0.252/0.014 ms $ ndp -an Neighbor Linklayer Address Netif Expire St Flgs Prbs <snip> fe80::1:1%en0 0:8:a2:9:3b:b4 en0 7s R R > So I could get rid of it and get there a proper link-local address? > There's nothing improper about it, it's fine as-is. _______________________________________________ pfSense mailing list https://lists.pfsense.org/mailman/listinfo/list Support the project with Gold! https://pfsense.org/gold
