Hello, everyone I am running an OpenBSD 6.9 Vultr node. Vultr is issuing /64 prefixes with SLAAC. I have a few machines behind this node, connected via wireguard.
For simplicity, let us say that vio0 is the default interface, configured the way Vultr suggests: hostname.vio0 dhcp inet6 autoconf -temporary -soii wireguard is configured like this: hostname.wg0 inet6 <a-static-ip-from-vultr-prefix> 128 !/usr/local/bin/wg setconf wg0 /etc/wireguard/server.conf from the outside I cannot pint <a-static-ip-from-vultr-prefix> , the response being 2401:c080:1c00:a4::33 icmp_seq=3 Destination unreachable: Address unreachable If my understanding is correct, that is because wg0 cannot respond to ND requests from the router. Trying to set up proxy NDP, I am running ndp like thi: ndp -s <a-static-ip-from-vultr-prefix> <vio0-mac-address> temp proxy If I understand correctly, this should make "vio0" announce the static ip to the router. (the words "temp" and "proxy" seem to have no effect) However, ndp errs: ndp: set: cannot configure a new entry There seems to have been a similar error in 2008: http://openbsd-archive.7691.n7.nabble.com/error-with-ndp-only-on-sparc64-td200752.html and https://marc.info/?l=openbsd-ipv6&m=120731349004033&w=2 sysctl: net.inet6.ip6.forwarding=1 but net.inet6.ip6.accept_rtadv=0 seems to have disappeared. What is it that I am doing wrong? The nabble message mentions some bug in ndp, but it should have disappeared long ago. Perhaps, an FAQ entry related to ndp would be nice to have? Ipv6 is supposed to have the adoption rate of 33%, not such an uncommon thing any more. -- Your sincerely, Vladimir Nikishkin (MiEr, lockywolf) (Laptop)
