[quote=anthomedal post_id=80230 time=1532696007 user_id=44657] First that's what I can do actually : Connect to server with client with any internet connection. But when I connect, I can't use the web.

Thank you TinCanTech, I will look that. I precise, the first topic is solved, not the second, don't close the topic please

I tried with the rule and this config : [code] local 192.168.0.10 port 1194 proto udp dev tun ca keys/ca.crt cert keys/server.crt key keys/server.key # This file should be kept secret dh keys/dh2048.pem server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt push "route 10.8.0.1 255.255.255.255" push "route 10.8.0.0 255.255.255.0" push "route 192.168.0.0 255.255.255.0" ;push "redirect-gateway def1 bypass-dhcp" push "redirect-gateway def1" push "dhcp-option DNS 10.8.0.1" client-to-client keepalive 10 120 user nobody group nogroup persist-key persist-tun status openvpn-status.log verb 3 explicit-exit-notify 1 [/code] And that don't work (no web connection)... Anyone has an idea ? Thank you !

Make sure your iptables is using the correct rule. (See above)

The commands that I run after server booting : [code] iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE service openvpn restart service openvpn status service openvpn stop service openvpn status [/code] I copied your command :/

Can you ping 8.8.8.8 from both the server and the client when the client is connected to the VPN ?

I can ping 8.8.8.8 from the server but can't with the client. (when the client is connected to the vpn)

TLS Error

anthomedal

That's done since the begining :

/etc/sysctl.conf:
net.ipv4.ip_forward = 1

TinCanTech

According to your tcpdump the packets from the VPN client IP do not emerge from the server. None of them ..

All I can suggest is that you clean up what you have now and start again ..

anthomedal

Clean all keys and certificates and restart all ?

TinCanTech

Your current certs and keys will be OK .. but I have no idea about your network.

anthomedal

So what clean up ?

anthomedal

Should I try with this : https://openvpn.net/index.php/access-server/download-openvpn-as-sw/113.html?osfamily=Debian ?
