I'm firewalling an Ubuntu Core 16.04 host: What port does snap package management require to be opened?
I spent ages Googling this: Snapcraft's docs don't detail the port nor did any other forums. Couldn't use tcpdump to derive the required port as snap find tcpdump gave no joy.
In the end, I had to packetsniff on the router. I'll provide the answer to hopefully save others firewalling Ubuntu Core hosts the same exercise in frustration...
snap firewall ubuntu-core ufw

In addition to allowing DNS of course, Ubuntu Core requires TCP/443 connectivity for snap package management to check for updates & install packages. The Ubuntu Core host on 192.168.1.26 is using a port from the Dynamic/Private port range, TCP/35234

Doing a host lookup of host 91.189.92.20 reports the remote IP as Snapcraft's:
20.92.189.91.in-addr.arpa domain name pointer api.snapcraft.io.
Anyhoo, hope this saves others some time-
