Push routes to clients? #559

Open stan-thomas opened 1 year ago

stan-thomas commented 1 year ago

The login page in my case is on a server connected to the router over a VPN. Coova-chilli is also on the same router. I would like the login page to be served over the VPN network.

Can coova push routes to connected clients?

In that particular scenario, you shouldn't need to push a route to wireless clients, if the VPN tunnel is terminating on the router, and the router is the default gateway for wireless clients.

I don't know if I have explained correctly. The VPN is not for private internet access, only point to point VPN connection. So if the login page is on 10.10.10.20 and the client device has an address of 192.168.200.20, the 2 cannot communicate. I think pushing the route to the client should solve the issue, but I find no particular way to do so.

Do note the internet gateway address is not in the "10.10.10.x" range. It is, for example, 172.16.2.1.

What I'm suggesting is that you need to deal with routing where the VPN tunnel terminates, I made the assumption that the VPN terminates on the internet gateway which for example is 172.16.2.1. The routing details do not need to be pushed to the wireless clients, they are handled on the default gateway they are pointing to.

Ah, in that case it does not happen as you have suggested. I cannot access anything on the VPN side of this from a client device. Correct me if I'm wrong, I think coova by default does not allow this.
