Test more servers & ports to ensure connectivity for On-premise Data Gateways

Hi,

the On-premise Data Gateway connectivity test is great.

But, can you please make sure you test all domain ranges that are required for the DGW? i.e,. the ones listed here:

https://learn.microsoft.com/en-us/data-integration/gateway/service-gateway-communication

Also, it would be good to include the proxy setting test to include the required config file for Fabric to work with a proxy:

`C:\Program Files\On-premises data gateway\FabricIntegrationRuntime\5.0\Shared\Fabricworker.exe.config`

Thanks,

Max
