Are there any changes in the IPv6 configuration? I have multiple machines. Some are still on 12.2 and one on 13.0. I have configured both as described in the handbook for IPv6. The 13.0 machine can ping the router just fine and the router shows in ndp: Neighbor Linklayer Address Netif Expire S Flags fe80::120c:6bff:fee9:cdf7%bge0 10:0c:6b:e9:cd:f7 bge0 23h33m12s S fee1::230 68:5b:35:d3:4e:da bge0 permanent R fe80::6a5b:35ff:fed3:4eda%bge0 68:5b:35:d3:4e:da bge0 permanent R The first entry is the router. Its a real router, not a FreeBSD machine. On the 12.2 systems I get from ndp: Neighbor Linklayer Address Netif Expire S Flags fee1::250 38:c9:86:07:3b:5b bge0 permanent R fe80::3ac9:86ff:fe07:3b5b%bge0 38:c9:86:07:3b:5b bge0 permanent R The router doesn't show and ping6 of it's address yields: PING6(56=40+8+8 bytes) fe80::3ac9:86ff:fe07:3b5b%bge0 --> fe80::120c:6bff:fee9:cdf7%bge0 Nothing more for quite awhile. I suspect there is a configuration item needed in 12.2 that is no longer needed for 13 but I haven't figured out what that would be. I have confirmed that the 12.2 system is receiving the router advertisements. They are just being ignored. -- Doug
