Why are NWA1123-ACv2 trying to connect to various internet-hosts
I noticed that my NWA1123-ACv2 access points are trying to contact various internet-hosts on ports tcp:4335 and tcp:6667, and they do so every 1-3 minutes. At the moment I counted 4 different target IP-adresses which are all in "eu-west-1.compute.amazonaws.com". The access points have a local configuration, not Nebula-connected, and so should at most try to connect to an ntp-host over udp:123.
Why do they try to connect and if a connection is successful, what data is transferred?
PS. if I try to connect to them over a webbrowser, why do I always have to click away this Nebula-page? If it has a local config, why not go directly to the local login?
