Synology: Default gateway metric not working

janhoedt

Hi,

When I connect an openvpn client, I can succesfully connect, but I cannot ping (error = expired in transit).
No specific change is done but I can see my default gateway isn't succesfully taken.
In my vpn config (client), I added
route 192.168.0.0 255.255.0.0 192.168.31.5 2 to direct 192.168.0.0 to correct vpn address.
Only 192.168.0.0 should go over openvpn.

Please advise.
J.

This is my route print:

What version of openvpn are you using on your server and clients ?

janhoedt

Synology OpenVPN and client version 1.0.3 (the only portable version I found).
It seems a client issue since I do can connect.

I did install the latest version of the client but the result is the same.

Found the root cause but not the solution. The TAP32 adaptor is not getting the ip (it says "disconnected" althought the Openvpn client says it does).

Ethernet adapter Local Area Connection:

Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :

Ok, sorry, fair enough.
Though I have a solution already = disable/enable windows TAP adapator. Problem solved now.

Well .. a work around not a solution .. but what ever works for you.

That is not the version of OpenVPN .. I suggest you make sure your OpenVPN installation is up to date.
