I'm not aware of any change that would cause this, port access is port access and should work regardless. You can check the Settings> Logs> Firewall Log (latest entries at the bottom) to see if the port rules are being actioned ok, should say 'session matches user pinhole, packet passed'. If you like you can give us a call while on-site and we can remotely access yourself and check the router settings to ensure the port rules are still in place and correct after the upgrade.
