--- Comment #4 from Vladislav V. Prodan <ad...@support.od.ua> --- (In reply to Andrey V. Elsukov from comment #3) >> Read the description of the bug again. >> I described how I managed to get the ipv6 to work. >It is wrong, and this is why it doesn't work. It's someone who did not quite correctly implement the IPv6 implementation in FreeBSD. I can give a working example for Debian, there is the same crutch in the destination route for the default router. >> ifconfig_em0_ipv6="inet6 2001:41d0:e:XXX::1/128" >What is the reason of /128 prefix length? So decided marketers in the OVH. I already pointed out to them that there are a number of vulnerabilities related to the substitution of IPv6 addresses. Personally, I only need one ipv6 address. >> ipv6_static_routes="ipv6gw" >> ipv6_route_ipv6gw="-host 2001:41d0:000e:03ff:ff:ff:ff:ff -iface em0" >This will not work on FreeBSD due to implementation specificity. Why not? It works the same. # netstat -rn6 Routing tables Internet6: Destination Gateway Flags Netif Expire ::/96 ::1 UGRS lo0 default fe80::12bd:18ff:fee5:ff80%em0 UG em0 ::1 link#2 UH lo0 ::ffff:0.0.0.0/96 ::1 UGRS lo0 2001:41d0:e:XXX::/56 link#1 U em0 2001:41d0:e:XXX::1 link#1 UHS lo0 ... 2001:41d0:e:3ff:ff:ff:ff:ff 00:22:4d:ad:ff:dc UHS em0 ... fe80::/10 ::1 UGRS lo0 fe80::%em0/64 link#1 U em0 fe80::222:4dff:fead:ffdc%em0 link#1 UHS lo0 fe80::%lo0/64 link#2 U lo0 fe80::1%lo0 link#2 UHS lo0 ff02::/16 ::1 UGRS lo0 >When the kernel is going to send IPv6 packet, it does L2 lookup to determine >L2 address.

I have an IPv6 router address by default. So what if he's not in the L2 segment? The network interface, where this Ipv6 is located, I know. Next, with these packages, the switches and routers of the hoster will be sorted out. I have a typical network scheme for many hosters dedicated servers. I have a test machine with which I can work for a while to correct this abnormal behavior. If you have the time and the desire to eliminate this, in personal correspondence I will provide access to the server. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
