Hello,

Ik bought a RUTX10 to replace a RUT950 as a Openvpn server.

i configuerd the device exacly the same, and the clients can connect to the new Openvpn server except i'm not able to ping the local ip-adres (the one that is routed) from the client.

Settings:

TUN

TCP

1194

LZO Yes

TLS

AES-256-GCM

TLS cipher All

Virtual network ip adress 10.8.0.1

Virtual network netmask 255.255.255.0

Push option Route 10.54.1.0 255.255.255.0 enz.

TLS Clients:

vpnclient1 10.54.1.0 255.255.255.0

On the RUT950 this works perfect, Can someone tell me what i'm doing wrong?

Hello,

Regarding your configuration kindly make sure that the RUTX10 is having the correct IP address. Because mainly you need to have a Public IP address to host the OpenVPN server. Other than that make sure you uploaded the correct certificate files. Sharing with me a copy of the troubleshoot file of the OpenVPN Server and the OpenVPN Clients will be helpful to identify what seems to be wrong.

Thanks

Regards,
Jerome

Hi Jerome,

The clients are connecting, so my guess is that my config is correct. but instead of routing the adresses that are giving at "Push option" the server is giving me the following notice:

Wed Mar  9 04:33:22 2022 daemon.notice openvpn(gbs)[12019]: vpnclient1/176.83.143.131:4310 MULTI: bad source address from client [13.94.132.101], packet dropped              

                                                                                                                                              

Server Config

The config from the clients haven't changed since this was a 1 on 1 replacemend for the RUT950 who was acting like a openvpn server before.

After completely opening the firewall i get the following result:
