Hello,

if this information is present somewhere in Forum, then please redirect me there, but I could not find anywhere on internet or this forum.

I need information about what ports does iThen.Measurements uses to do its Measurments. I am using Linux server with very strict firewall rules, so I am not sure if my current rules allow iThena.Measurments to run as ir should.
To the outside I am allowing just TCP/UDP 53, TCP 443, TCP 80 and TCP 123. Incoming policy is even more strict.
Before adding these strict rules I saw, that the server sends UDP packets with size around 78 bytes, maybe these packets were from iThena, but I am not sure.

Can anyone help me with this, is this information known?

PS. I am running Ubuntu 22.04.4 LTS, kernel 5.15.0-94-generic and Boinc version 7.18.1, but this probably is not needed information.
