My Windows 10 client Routing throught vpn is working, pinging signal and other type of request (http, git, ...) also go through the VPN interface

only access windows sharing folder is not - it always go through default gateway , cause of my client's gateway is able to connect direct to the server.

If I delete the route to the default gateway, then the accessing to Shared folder is through the VPN

How can I fully route to the server without delete the default route. The shared folder server is 10.10.2.195

This is route table ( I also changed the route metric, but it is not working for access shared folder \10.10.2.195)

And after delete (then it works - accessing Share folder work through the VPN)

route delete 0.0.0.0 mask 0.0.0.0

How can I fully route (accessing shared folder) to the server via VPN without delete the default route?

The only odd route in there is 0.0.0.0/1. Apart from that it looks entirely fine; most specific route should win, so your /24 for 10.10.2.0 should win over the generic /1 and /0's which is default routes. What VPN do you use?

@vidarlo vpn server is setup by my self, Yes, everything look fine, all of other request (ping, http, git,) to server is going through vpn already, only acccessing shared folder is not, I also check on other client running windows 7 or ubuntu , it works normal. this issue is only happened in windows 10 client.

Out of curiosity - could you test with the 0.0.0.0/1 route deleted as well?

It sounds like you want to access a shared folder on a server over a VPN connection, but your client's default gateway is preventing the traffic from going through the VPN.

One way to route the traffic for the shared folder through the VPN would be to create a route on your client's machine specifically for the IP address of the server.

To do this, you can use the "route" command in a Command Prompt or PowerShell window. The syntax for adding a route is as follows:

route -p ADD 10.10.2.195 MASK 255.255.255.0 10.71.0.10 metric 1

This will add the route to the client's persistent routing table, so it will remain even after the machine is restarted.

If you read the routing tables posted you will see that they are in fact correct...

I tried your route command, and there is no change. I think that route is included in the table I posted already ``` 10.10.2.0 255.255.255.0 10.71.0.9 10.71.0.10 27 ```

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
