Our company will setup mobile devices which use private mobile network (special sim card which blacklist all urls and allow for only specific urls).
(Our company has a firewall and it is preventing our enterprise mobile app from sending analytic events to Firebase via the SDK.)
We have a scenario to use Firebase-analytic to log user events. So far I am trying to find what are the urls or IP addresses which device will request to firebase-analytics when logging but I could not find any network information.
All network information for firebase which I could get is only network for FCM (port 5228-5230). However, I couldn't find any information about firebase-analytics.
In conclusion, what are urls/ip addresses and ports which should I need to open for using firebase-analytics in this private network?
Thank you.
After investigating, I understand that firebase will connect to the to Google's ASN of 15169 (https://ipinfo.io/AS15169) via port 443 (HTTPS) but my company does not allow to config firewall for 485 rules (refer to 485 subnets in AS15169).
I tried to troubleshoot by enable debug log on android but does not see any URL like it was mentioned in Alowing Firebase Analytics domain names without allowing other Google services
Thank for the answer in this topic, right now we found that we should whitelist an url for firebase analytics as https://app-measurement.com
