openVPN routing - Windows client


Hi,

I've just configured my first openvpn server. It works. I can connect to it. My internet connection doesn't work anymore, but that's not the problem in itself. I need to get the iptables rules and some push directives right.

Windows uses 10.0.2.0/24 as the local network, with 10.0.2.1 as gateway. The internet works fine when I'm not connected to the vpn.

the VPN lan is 10.8.0.0/24.

But what is strange is that when I write "route print" in the command line, it says:

network destionation: 0.0.0.0
network mask: 0.0.0.0
Gateway: 10.0.2.2
interface: 10.0.2.15
metric: 10

And the second row:
network destionation: 0.0.0.0
network mask: 128.0.0.0
Gateway: 10.0.2.0
interface: 10.8.0.6
metric: 20

So my question is, why is the data being routed through the second gateway, if the first has a lower metric?

This doesn't look like the complete story. Is that the entire routing table output? If not, it might be helpful if you just mark/paste the windows output so that the original formatting is also preserved

255.255.255.255 255.255.255.255 On-link 10.0.2.15 266
Indeed, now I see that in the row where my server's ip shows up, the metric is also 10. So the more specific networks have priority?

In a word, yes.
