I have been testing these changes for several weeks on 10+ various hosts, including servers and routers, and I only see positive changes.

It will be the same value as defaults for net.inet.icmp.icmplim. In my case it was required to silence spurious warnings on two web servers and BGP router. > The value 100 of tunable `net.inet6.icmp6.errppslimit` dates back to 2000, the first time it was introduced [1]. I do not find any RFCs that has recommendation value for it. RFC 4443 section 2.4 (f) [2] has an example default of 10 that is much smaller ( for small/mid-size devices ). I expect the default value of net.inet6.icmp6.errppslimit will stay 100 for much longer time ;) 1. https://cgit.freebsd.org/src/commit/sys/netinet6/in6_proto.c?h=stable/7&id=686cdd19b1b182f2257bc158116e78c5fef84980 2. https://www.rfc-editor.org/rfc/rfc4443.html#section-2.4 Best regards, Zhenlei > With best regards, > > -- > Marek Zarychta
