Norton Core Outbound Ports Used
Setting up the Norton Core behind by ISP gateway (the latter was not setup in bridge mode, but port 80 and 443 are allowed), I found the mobile app stating that it can't connect to the cloud. Upon allowing all outbound connections on the gateway, I was able to complete setup.
Upon loss of http/https communication (i.e. gateway down), the app states that network status is offline. Upon restoration, the app still says network status offline. Upon allowing outbound connections, the network status changes to online.
Not sure if the above events are all related somehow, but this is the basis for my suspecting that certain ports are required to use the Core. I am unable to find any documentation regarding what ports are required for the Core to communicate with Norton servers. Since the Core does not block outbound connections by port (which is something that improves security by blocking all ports and only allowing traffic through approved ones), I need another firewall to do that. To be clear, this is all about outbound connections, not inbound connections, However, I want to allow ports that are required by the Core. This should not be a secret, as security though obscurity is considered a bad idea. Not sure if its just one port, or a random port selected within a certain range. What are those ports? Thanks!
