Azure P2S client traffic to S2S network

Question

My VNet won't allow me to connect to the s2s location via p2s connection.

I'm trying to connect the Azure VPN client on my machine and reach a site that is allowed in a network which I have a s2s connection to.

Here's the thing, I can't get traffic to flow from my pc running the VPN client, out to the target site.

Topology

PC > VPN Client > VNet via p2s > Remote network via s2s > FTP server

I'd like to be able to ping the FTP server from my machine. Currently only devices in the VNet can ping.

I tried setting up BGP but it broke the connection, as I don't really know how things should be set.

I don't have access to the remote site or it's devices. I have a Azure local network gateway which is configured as the s2s location.

I'm sorry if that doesn't make sense.

Edit: here is the picture of the network

Answer 1

My solution to this as I can't enable BPG is to use a proxy server within the VNet.

Answer 2

BGP is the standard routing protocol which enables the Azure VPN Gateways and your on-premise VPN devices to exchange "routes" that will inform both gateways on the availability and reachability for those prefixes to go through the gateways or routers involved.

To configure the BGP, your on-premise device should also support BGP. Read

• What address does Azure VPN gateway use for BGP Peer IP?
• What are the requirements for the BGP Peer IP addresses on my VPN device?
• What should I specify as my address prefixes for the Local Network Gateway when I use BGP?

Without BGP, If you add the point-to-site addresses after you create your site-to-site VPN connection, you need to update the routes manually. You need to manually add the routes to the remote network on your machine.

For more information, you could refer to configure and validate virtual network or VPN connections. Except the Ping tool, you prefer to use TCping tool, see the detailed steps.
