Hi, i configured an OpenVPN server on my Raspberry and i used this simple configuration (server.conf): [code]dev tun ifconfig 192.168.1.5 192.168.1.6 secret static.key port 1194 status /etc/openvpn/openvpn.log push "dhcp-option DNS 8.8.8.8"[/code] Instead, on my client (Windows laptop) i use this client.ovpn file: [code]remote ***.ddns.net dev tun ifconfig 192.168.1.6 192.168.1.5 secret static.key dhcp-option DNS 8.8.8.8[/code] Unfortunatly, at work i use a domain account and the default DNS is a DNS server of my company. I want use the VPN to access to Facebook, Instagram and other blocked site. The VPN works (i can connect and surf the internet) but when i try to access for example in Facebook, my DNS company block me. How can i use an open DNS when i connect with the VPN? Thanks a lot Christian

Problem with DNS!!!!!

Hi,
i configured an OpenVPN server on my Raspberry and i used this simple configuration (server.conf):

dev tun
ifconfig 192.168.1.5 192.168.1.6
secret static.key
port 1194
status /etc/openvpn/openvpn.log
push "dhcp-option DNS 8.8.8.8"

Instead, on my client (Windows laptop) i use this client.ovpn file:

remote ***.ddns.net
dev tun
ifconfig 192.168.1.6 192.168.1.5
secret static.key
dhcp-option DNS 8.8.8.8

Unfortunatly, at work i use a domain account and the default DNS is a DNS server of my company. I want use the VPN to access to Facebook, Instagram and other blocked site. The VPN works (i can connect and surf the internet) but when i try to access for example in Facebook, my DNS company block me. How can i use an open DNS when i connect with the VPN?

Thanks a lot

Hi,
i tried this solution but it doesn't work:

Client configuration: remote ***.ddns.net
dev tun
ifconfig 10.8.0.2 10.8.0.1
secret static.key
push "dhcp-option DNS 10.8.0.1" Server cnfiguration: dev tun
ifconfig 10.8.0.1 10.8.0.2
secret static.key
port 1194
status /etc/openvpn/openvpn.log
push "redirect-gateway def1" I don't know why.....

Please do not post details of your server DNS name or IP.

ducarpit wroteServer
..
push "redirect-gateway def1"

You cannot push directives from your server with static key VPN.

Therefore, add:

redirect-gateway def1

to your client config.

A better solution is to follow the HOWTO and set up your VPN as documented :
https://openvpn.net/index.php/open-source/documentation/howto.html

Hi,
thanks for the reply.
I tried this configuration:

remote *******ddns.net
dev tun
ifconfig 10.8.0.2 10.8.0.1
push "dhcp-option DNS 10.8.0.1"
redirect-gateway def1

dev tun
ifconfig 10.8.0.1 10.8.0.2
port 1194
status /etc/openvpn/openvpn.log
push "redirect-gateway def1"

I deleted the static key (in the server and also in the client) and add redirect-gateway def1 in the client.
But now i can't access any site.

it will never work if you don't take the time to read the man page and learn how it work and why 🙂
FYI your server will have to do ip forwarding (like a router and possibly NAT too)

TiTex wroteit will never work if you don't take the time to read

Not sure they even read what I posted:

TinCanTech wroteYou cannot push directives from your server with static key VPN

Followed by:

ducarpit wrotedev tun
ifconfig 10.8.0.1 10.8.0.2
port 1194
status /etc/openvpn/openvpn.log
push "redirect-gateway def1"

All openvpn directives are documented in The Manual v24x

ducarpit wroteI think the problem was the secret static.key in the server configuration file, so i decided to delete it.

Do not jump to conclusions .. nobody said the static.key was a problem but you really need to read the HOWTO and setup the example server and client.

Hi,
i solved my problem using another guide. At the moment the VPN works fine, and i am studying the configuration file to understand how it works.
Thanks to all

Hi, I have followed the official guide. I have followed other guides...still not working :-D

I have no DROPped packets by firewall...even if I switch off firewall it still not works.

I suspect it is some limitation on VPS with old kernel that cannot be upgraded.

Can anyone point me where should I look, please?

I don't see any errors in log...except

ping: Temporary failure in name resolution

I suspect DNS and routing have been not changed properly

10.8.0.5 dev tun0 proto kernel scope link src 10.8.0.6 
10.8.0.1 via 10.8.0.5 dev tun0 
116.203.54.160 dev venet0 scope link 
0.0.0.0/1 via 10.8.0.5 dev tun0 
128.0.0.0/1 via 10.8.0.5 dev tun0 
default dev venet0 scope link

it is weird because tun0 has got 10.8.0.6 and venet0 is still default route despite forced gateway and DNS

Any suggestions, please?
