This is the result of Netmetr performed by Android 10 on my line with Turris Omnia and Turris OS 3.11.8. There are these two ports (123 and 5060) on UDP that are blocked. It’s normal? In Netmetr it is reported as an error.
This test is from internet to youre extern IP ?
Yes, do you think my ISP is blocking them?
Are you testing the direction out or inside ? In the direction from the Internet to the LAN, all ports are closed if (until) the data collection is not Haas-proxy or other port forward in firewall
123 … ntp - network time protocol
5060 … The Session Initiation Protocol ( SIP) is a [signaling protocol] used for initiating, maintaining, and terminating real-time sessions that include voice, video and messaging applications. SIP is used for signaling and controlling multimedia …
All ports should be open outwards if the provider is not blocking. I would understand the blocking of ports used need email servers to prevent the function of spam bots. For ports 123 and 5060, I don’t see a reason to block. Ask your provider.
I use to check which my port are open to the Internet https://www.grc.com/x/ne.dll?bh0bkyd2
Reverse direction out I have no reason to check because all my apps are working
Error on ports be me:
TCP 25 and 53
UDP 53, 123 and 5060
25 is SMTP … block email spam from mail server (in youre LAN)
53 … DNS server (youre router does not serve as DNS for Internet)
123 … Network Time Protocol (youre router does not serve as time server for Internet)
5060 … telefonie (Messenger au Skype is ready ?)
You shouldn’t be nervous-I think it’s a logical security measure that doesn’t affect your connection function
In fact it doesn’t seem to be a problem. It was just to understand what it could depend on.
