[atlas] Probe and firewall settings?

Hi, At https://atlas.ripe.net/about/faq/#so-which-services-do-i-need-for-my-probe-t... it says "The absolute minimum set is DHCP, DNS and outgoing TCP port 443 (HTTPS) in order to allow the probe to connect to the network. However, this in itself is not enough to do measurements, which is the entire focus of RIPE Atlas, so you should also allow ICMP, UDP (DNS + traceroute), TCP for traceroute and HTTP(S)." What specific ports and protocols are required for routine operation and for inbound or outbound measurements to be configured? I think the above info could be a little more detailed (having had questions asked of me). Many thanks, Tim
