Hi everyone, I've been setting up IPv6 on the various networks I look after over the = last weeks. Today the turn came to a system that's running two FreeBSD = boxes with carp etc. I added an inet6 address to the ethernet interface and then the 'carp = address' to carp0. The carp address is used by our upstream provider. = Things appear to work except I can't ping the carp address -- even from = localhost! carp0: flags=3D49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 207.171.2.194 netmask 0xfffffff8=20 inet6 2607:f238:0:11::2 prefixlen 125=20 carp: MASTER vhid 110 advbase 1 advskew 100 If I from the box itself ping this ::2 address, 'tcpdump -nn -i lo0' = says: 06:57:47.606443 IP6 2607:f238:0:11::2 > 2607:f238:0:11::2: ICMP6, time = exceeded in-transit for 2607:f238:0:11::2, length 64 06:57:47.606472 IP6 2607:f238:0:11::2 > 2607:f238:0:11::2: ICMP6, time = exceeded in-transit for 2607:f238:0:11::2, length 64 06:57:47.606502 IP6 2607:f238:0:11::2 > 2607:f238:0:11::2: ICMP6, time = exceeded in-transit for 2607:f238:0:11::2, length 64 06:57:47.606531 IP6 2607:f238:0:11::2 > 2607:f238:0:11::2: ICMP6, time = exceeded in-transit for 2607:f238:0:11::2, length 64 06:57:47.606560 IP6 2607:f238:0:11::2 > 2607:f238:0:11::2: ICMP6, time = exceeded in-transit for 2607:f238:0:11::2, length 64 If I ping the ::2 address from another box, the relevant interface shows = the same response. Any ideas? - ask=
