I have just set up a balenaOS rpi 1, development version. I can connect locally and can ping out to internet so I am sure the device is working fine but I can’t get dns lookup from the device and it is not showing on cloud dashboard. It is behind a firewall, no outbound restrictions. What ports do I need to forward to the pi on the inbound, is it just 443 or do I need 53, 123, others?
Hello,
In addition to TCP 443 (for VPN), ports UDP 53 (for DNS) and UDP 123 (for NTP) are used. However outbound only is usual sufficient (though may depend on the specifics of the rules). You may also need to whitelist the following domains for these ports:
- *.balena-cloud.com
- *.docker.com
- *.docker.io
See: https://www.balena.io/docs/faq/troubleshooting/faq/#what-network-ports-are-required
Thanks for that, it did have access to all those ports but had picked up the wrong gateway address. Connectivity sorted now.
