Static Route to Subnet via VPN

routingvpn

Trying to access a network via a static route.

My PC is on Windows 10 and I am connecting to a remote network via VPN.
My local network is 192.168.178.1/24.
My PC's VPN client address is 10.35.0.144.
The VPN gateway is 10.35.0.129.

Via the VPN I have access to a 10.1.0.0/24 network, where a router, IP: 10.1.1.175, enables access to another 10.124.193.0/24 network.

I need to be able to manage devices on this 10.124.193.0/24 network. I added a static route: "route add 10.124.194.0 mask 255.255.255.0 10.1.1.175", which I thought might do the trick.

However, when I do a tracert to 10.124.193.x, I see that traffic is not going through the VPN as expected, but hits my local gateway (192.168.178.1) and stops there. I expected a couple of hops like: 10.35.0.129, then 10.1.1.175, then 10.124.193.x.

The output of the route table below is partly in German, I hope that is ok, and still comprehensible.

C:\WINDOWS\system32>tracert 10.124.193.6

Best Answer

When you set a route, you need to give it the next hop. In your case, the next hop is 10.35.0.129, but your configured next hop is not.

After that, you are trusting that the next hop has a route to then next hop in the path toward your destination. If not, you need to modify that router to have a route toward your destination. If you don't have access to that router, this question is off-topic since you need to have control over the network about which you are asking questions.
