TC56 resolve intranet IP addresses

Hi all,

we're currently implementing a new ERP solution (MS Dynamics 365)  and want to use TC56 devices for logistics. For certain use cases we need to access the ERP via GSM / VPN. The ERP System has an internal dns Name and internal IP address. I already learned that there is no propper way to add the erp hostname in the Hosts file in android. I cannot change the  hostname to be external accessable. Has anyone an idea how I can resolve this issue?

- Is there a way to Change the DNS Server in Android to a local one which could be accessed via VPN from the OS or add another DNS on top of the given DNS Server from the Provider

- Is there a Software solution which could help us here to fix this issue?

Any ideas are welcome.

Best regards

Stefan Vogel
