Good afternoon!
I'm trying to configure a VPN server in Ubuntu using openVpn. I already configured the server.conf file and the client.conf file (one of my vpn clients is a Windows virtual machine and the other one is an Ubuntu VM). These are my configurations:
Server.conf
port 1194
proto udp
dev tun
ca ca.crt
cert grupo04vpn.crt
key grupo04vpn.key # This file should be kept secret
dh dh2048.pem
server 10.0.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push "route 172.17.20.0 255.255.255.0"
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 172.17.20.4"
client-to-client
keepalive 10 120
comp-lzo
max-clients 100
persist-key
persist-tun
status openvpn-status.log
verb 5
Client.conf
client
dev tun
proto udp
remote 172.17.20.6 1194
resolv-retry infinite
nobind
persist-key
persist-tun
ca ca.crt
cert client.crt
key client.key
ns-cert-type server
comp-lzo
verb 3
I'm able to ping 10.0.0.1 (which is the server's ip) from the vpn client, and i'm able to ping 10.0.0.10 (which is the client's ip) from the vpn server. However, when i check the tun0 interface from IPTRAF i see that no traffic is going through tun0, only through eth0. Here you can see a screenshot from iptraf when I ping 10.0.0.1
eth0: eth0 iptraf
This is my network topology
As you can see all the traffic is going through the eth0 interface, and i guess it should go through tun0. I would really appreciate any help to make traffic go through the tunnel as it should be.
Thanks.
UPDATE: This is the output of netstat -rn
