https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D286322 --- Comment #18 from Paige Thompson <paige@paige.bio> --- 2 things I almost forgot:=20 - the NDP entries are listed as permanent so I'm not sure if that implies t= hat they are configured from discovery or if they were made static=20 - On linux I'm not sure what the equivalent would be to: net.inet6.ip6.source_address_validation unless it is net.ipv6.conf.all.accept_source_route because I was thinking "rp_filter" was it, but that's not even an option for IPv6 on Linux.=20 https://www.tenable.com/audits/items/CIS_Ubuntu_18.04_LTS_Server_v2.0.1_L1.= audit:e9984a0cc2171684ec9f44206b4b52b6 https://lists.freebsd.org/archives/dev-commits-src-all/2021-November/001801= .html <--- from this description, it actually sounds more like Linux equivalent t= o:=20 net.ipv6.conf.all.accept_redirects =3D 0 net.ipv6.conf.default.accept_redirects =3D 0 (I checked and made sure they = were all set to 0 and one is still reachable from the other.)=20 It's weird to me that I can't find any rp_filter stuff for IPv6 on here tho= ugh.=20 But yeah I mean take the fact that "it works on other things" with a grain = of salt here. Also I might be missing the point of epair entirely, I don't rea= lly know what I would even use epair for except for maybe creating a patch betw= een two layer 2 bridges. I feel like I saw an example of how to use epair this = way, but I don't remember where and I don't think even veth was intended to be u= sed this way but you can at least (there are problems, just different problems.) --=20 You are receiving this mail because: You are the assignee for the bug.=
