Connected to VPN but not getting response
Posted: Thu Mar 26, 2020 8:15 pm
I'm connecting with openvpn client for linux in a Fedora 31 machine to a OpenVPN network. I'm using the command
The connection is succesful, as after the connection, the log ends with the message
The network interface appears correctly, and the routing table is updated accordingly. Ifconfig shows the new interface
and route -n gives
However, I can't connect to any host on the VPN, obtaining a timeout error every time. Using wget, git or browsing to any of the servers on the VPN gives a timeout error, even though they are correctly routed on the table. Inspecting on wirehark, I discovered that the TCP SYN packet is sent, but a reply is never received, and my computer keeps retransmiting.
From other networks it's possible to connect correctly to the VPN. Even in the computer I'm using, I can connect with gnome's VPN client. However, this client is not ideal for my, as it completly bridges my pc, while I want to use the VPN just to access some hosts, as openvpn's client allows.
