Two-way Hybrid Connections - azure

I established a Hybrid Connection from App Service to on-premises by using Hybrid Connection Manager (HCM).
Is it possible to connect the other way from on-premises to the App Service?
This would be needed to have a two-way communication channel.
To be clear: I don't need any help regarding the setup of the Hybrid Conenction Manager. Everything is working fine. I also can reach the on-prem resource from App Service by using curl. So is there a way to curl the App Service from on-premises server where HCM is running?

Connect Azure Logic App to On Premise FTP Server using Azure Hybrid Connection

I am currently exploring a way to connect Azure Logic App to be able to fetch file from on-premise FTP server. What I have found in Azure documentation : https://learn.microsoft.com/en-us/azure/connectors/connectors-create-api-ftp#connect-to-ftp, that it is possible to do so.
If you have an on-premises FTP server, consider creating an
integration service environment (ISE) or using Azure App Service
Hybrid connections, which both let you access on-premises data sources
without using an on-premises data gateway.
So I am interested to use Azure App Service Hybrid connections for this, but what I don't know is how to connect ftp connector in logic apps to Hybrid connections set in Azure App service. The documentation for Azure Hybrid connection didn't mention about how to do this.
If anyone knows how to connect Azure Logic App to on-premise FTP server via Azure App Service Hybrid connections, appreciate your help on this.
Thanks
To create a Hybrid connection to FTP, try the following steps:
In Azure App Service, open Networking tab in the left pane
Go to Configure your Hybrid Connection endpoints
Click on Add hybrid connection
Click on Create new hybrid connection and add following information:
a) Hybrid Connection name
b) Endpoint hostname
c) Endpoint port
d) Service Bus namespace you want to use (Every Hybrid Connection is tied to a Service Bus namespace, and each Service Bus namespace is in an Azure region)
Then you can connect the App Service with the Logic App

Azure Web app for containers to on-premises connection

Currently i'm hosting an API in an azure Web App for Containers App Service. Additionally, I have a logging database hosted on an on-premises service which can't be accessed publicly.
For accessing the on-premises service it is possible to create a hybrid connection; however this feature is not available through the Azure portal when using Web App for Containers as opposed to when using just a Web App.
Is it possible to create this Hybrid Connection programmatically or through the CLI?
Are there other methods of connecting to on-premises resources through azure?
The API is using ASP.NET Core.
I have been looking into the Microsoft.Azure.Relay package, but I seem to be unable to actually reach my on-premises endpoint through the samples supplied by the package.
Edit:
I have verified that i can make the Hybrid Connection using a Web App. To do this i have downloaded the Hybrid Connection Manager, installed it on the on-premises network and checked that an application can make HTTP calls to the endpoint at the end of the Hybrid Connection.
All of this is done through the azure portal by going into my Web App, then navigating to Networking, configuring Hybrid Connections and creating a Hybrid Connection, and connecting to the new Hybrid Connection through the Hybrid Connection Manager.
What i'm not capable of is doing the same for my Web App for Containers, as Networking is not a supported tap (yet?). Therefore, i'm looking for a programmatical way of doing this either through the CLI or in the sourcecode.

Connecting to an Hybrid connection served by the Hybrid connection manager

I've made a couple of tests and, as far as I've understood, Azure Relay requires the listener to explicitly connect to the bus. In our scenario, we would like to use it from a VM in Azure (or a different system on Internet) to connect to an existing On-Premise resource that cannot be modified to support Hybrid connections. I've tested also the Hybrid Connection manager and I wasn't able to find any documentation on how to create a client that connects to a Hybrid connection that routes the traffic to the target system by using the Hybrid Connection manager. It works from an Azure Web app, but they are not a viable solution in our scenario.
Is it possible to use the Hybrid connection manager from outside an azure web app?
I've digged two days more to find an answer and from this article, it seems it's not possible:
https://learn.microsoft.com/en-us/azure/biztalk-services/integration-hybrid-connection-overview
Hybrid Connections provide an easy and convenient way to connect the
Web Apps feature in Azure App Service (formerly Websites) and the
Mobile Apps feature in Azure App Service (formerly Mobile Services) to
on-premises resources behind your firewall.
And it sounds correct since they requires some adjustments at network level that are made under the hood by Azure: the mobile app makes a specific dns query and the azure internal dns returns a 'ghosted' ip that offers an entrance to the hybrid connection tunnel at the requested port. The hybrid connection then 'forwards' the tcp stream to the on-premise hybrid connection manager that proxy the request toward the real ip of the service. In this way, hybrid connections does not breaks any SSL connections since the target dns host is the same of the final SSL endpoint.
However, digging a bit more, i've found two examples that offer a pre-elaborate that it's helpful in my scenario:
Hybrid Connections Reverse Proxy

Port Bridge

Unable to connect to SQL Server Analysis Services using Azure Hybrid Connection

We have configured the Azure Hybrid Connection in the App Service which we want to access the SQL Server Analysis Services from On-Prem server. The port configured in Hybrid Connection is 2383. The connection status is showing connected on both the Azure and in the Hybrid Connection Manager of the On-Prem server. But when we run the application it is throwing A connection cannot be made. Ensure that the server is running.
Most probably you might be having issue with TLS version that is currently enabled on your on-premises server. A detailed article on how to tackle each and every problem that you might be facing with the HCM can be found here.
Hope this might be sufficient to solve all your problems.

Azure VPN Configuration - Connect to existing VPN

I'm trying to connect my Azure Web App to an Existing VPN.
To connect to this VPN I must give to the admin some configurations, but I'm not sure of HOW can I provide them from Windows Azure.
As far as I have understand is all about creating the Virtual Network and the "connect it".
Like:
Create Virtual Network
Create Public Gateway
Create Local Gateway
Connect something somehow
https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-howto-site-to-site-resource-manager-portal
In my specific case, for the configuration, are required a lot of parameter that I don't know how / where to find:
VPN Endpoint IP
IKE (Encryption type, Authentication Method, Diffie-Hellman Group, Sec Lifetime, Preshared secret)
IPSEC (Perfect Forward Secrecy)
Network profile
In the docs there is a link to Check Point NGX and Microtik so I check out this tutorial:
https://blogs.technet.microsoft.com/netgeeks/2017/07/11/creating-a-site-to-site-vpn-ipsec-ikev2-with-azure-and-mikrotik-routeros/
But how can I get this parameter to perform the connection? Do I need to install extra software on my WebApp? How can I include my web app in the VPN?
And, is there any simplify way for Web App that does not include creating the whole infrastructure?
Thanks in advance
As EvilSnobu said, you can use Hybrid connections to connect your Azure APP service and your on-premises.
Hybrid Connections can be used to access application resources in other networks.
My understanding is that you have Azure Web App and you need to
connect to an on-premises network via VPN?
You are right, the Hybrid connection feature requires a relay agent in the network that hosts your Hybrid Connection endpoint.
You should download and install Hybrid connection manager (HCM) on your local machine and use it to connect to that app service.
