When I have tried to increase max table entries above 1 million, they do not increase and when I go back to the settings page it is still at 1 million. Has a limit been implemented?
I don't think so. I'm able to go back and forth between 1M and 2M under "Firewall->Settings->Advanced->Firewall Maximum Table Entries" and that's being reflected in the Aliases UI.

Are you seeing any errors logged and/or memory limitation?
