When adding Fleet agent environment variables for the proxy, replace <PROXY_IP> with your private proxy IP.
:::caution
The `NO_PROXY` environment variable is not standardized, and the accepted format of the value can differ between applications. When configuring the `NO_PROXY` variable in Rancher, the value must adhere to the format expected by Golang.
Specifically, the value should be a comma-delimited string which only contains IP addresses, CIDR notation, domain names, or special DNS labels (e.g. `*`). For a full description of the expected value format, refer to the [**upstream Golang documentation**](https://pkg.go.dev/golang.org/x/net/http/httpproxy#Config)
