Hi,
I'm trying to establish a VPN connection between our cloud infraestructure and an external provider's local network. I've configured a Site-to-Site virtual network in Azure Portal with no problems and I've been able to create the gateway.
I've provided the external provided with the gateway's public IP address and the pre-shared key for them to configure their router.
Now... when I try to connect the Virtual Network with the on-premises provider's network I just get the "could not enable the connection to local network" error in the Azure Portal and the provider is telling me that they are not receiving any incoming
package from my gateway's IP address. So, now I'm wondering....
1. Is it possible to troubleshoot this issue somehow... I mean, is it possible to get more information on what's happening?
First of all, I'm trying to detect where's the issue.... my side or the provider's one. But I'm not able to "see" what's happening when I click "Connect" in the Azure Portal.... so I have no clue.
2. Is it required to deploy at least a VM in my Virtual Network to make the connection succeed? Currently there're no resources allocated into the Virtual Network.
3. The provider's VPN device is not behind NAT.... is there anything else that may be causing this issue I should investigate?
Thanks.
