Issues reaching NTP service on openwrt, but ONLY when bound to an interface?

[lleachii]

NTP, I'm doing something wrong

First, NTP is UDP, not TCP. This explains why some of your tests ended up in no responses. Next: I have the same behavior, I haven't noticed a change since version 19 or 20. On a client: ntpdate -q 192.168.1.1 This works for me, which made me wonder why. The answer is IPv4-mapped IPv6 addresses. See: https://lwn.net/Articles/688462/ https://unix.stackexchange.com/questions/152612/netstat-why-are-ipv4-daemons-listening-to-ports-listed-only-in-a-inet6 root@OpenWrt:~# sysctl net.ipv6.bin…

@aleks-mariusz

also confirmed since when i do listen on a specific interface, i can't even reach it over IPv6 either :-/

How did you actually bind?

Perhaps I missed it in the thread.
