## Best practices

* **Note**\
  The administration endpoint should never be exposed to the public internet. Additionally, we recommend monitoring the administration endpoint logs, which are set by the `ENVOY_ADMIN_ACCESS_LOG_FILE` environment variable to `/tmp/envoy_admin_access.log` by default.
* **Note**\
  We do not recommend using the `debug` level in production environments. Setting the level to `debug` increases the logging and may affect performance and the overall cost of logs offloaded to solutions like [CloudWatch Logs](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html).

## Setup

* **Important**\
  Fargate must use a port value greater than 1024.

## Connectivity

* **Important**\
  While the standard SMTP ports are `25`, `587`, and `465`, you should only add the port you are using to `APPMESH_EGRESS_IGNORED_PORTS` and not all three.
* **Note**\
  Setting the mesh outbound filter value affects all virtual nodes within the mesh.
