We just switched (after several years running pfsense) to opnsense.
Besides others we activated IPS in IDS-service and the country-blocker with aliases.
One of them (dont know which) is blocking the navigation-icons in the calendar on calendar.gmail.com (we are using the gmail-suite), as shown in the attached screenshot. Up to now we did not see any other website with this problem.
Anyone knows how we can get the icons load again?
P.S.: at a different office which is still running pfsense, everything is displayed correctly
So when you disable geoip alias blocking they are back?
You are absolutely right, we should have tried that before: no, they are still gone, even if we disable both services, so it should be something else. Strange...
