Hi guys! I am using the OpenVPN Server on my Synology DS215j. It is connected to my Arris Router. I have a no-ip address. When I connect with my Windows 8.1 Notebook i can use the local network normally. When i use the Internet on my Notebook the traffic doesnt go over the tunnel as expected. If i change the config and redirect the gateway with this command (client): "redirect-gateway" and "dhcp-option "DNS 8.8.8.8" the whole traffic goes over the tunnel. As expected. But I have troubles with my Android Smartphone (Samsung Galaxy Note 3 - Android 5.0). If i use "redirect-gateway" and "dhcp-option "DNS 8.8.8.8" the whole traffic goes over the tunnel. But if I use none of the two options the DNS Service is not working. I can connect to google with the ip-Address. But i am not sure if the traffic goes over the tunnel or not. How can i configure the client/server, that my Android Smartphone is working correctly? I want to use my home-network over vpn and parallel the "normal" internet as on the notebook to achieve a higher speed? This is my server config: [code]push "route 192.168.0.0 255.255.255.0" push "route 10.8.0.0 255.255.255.0" dev tun management 127.0.0.1 1195 server 10.8.0.0 255.255.255.0 dh /var/packages/VPNCenter/target/etc/openvpn/keys/dh1024.pem ca /var/packages/VPNCenter/target/etc/openvpn/keys/ca.crt cert /var/packages/VPNCenter/target/etc/openvpn/keys/server.crt key /var/packages/VPNCenter/target/etc/openvpn/keys/server.key max-clients 3 comp-lzo persist-tun persist-key verb 3 #log-append /var/log/openvpn.log keepalive 10 60 reneg-sec 0 plugin /var/packages/VPNCenter/target/lib/radiusplugin.so /var/packages/VPNCenter/target/etc/openvpn/radiusplugin.cnf client-cert-not-required username-as-common-name duplicate-cn status /tmp/ovpn_status_2_result 30 status-version 2 proto udp6 port 1194 [/code] This is my client config (without redirect or dns): [code]dev tun tls-client remote "my external no-ip address" 1194 #redirect-gateway #dhcp-option DNS DNS_IP_ADDRESS pull proto udp script-security 2 ca ca.crt comp-lzo reneg-sec 0 auth-user-pass[/code] I hope you can help me!

FYI: [list]NOTE: your local LAN uses the extremely common subnet address [u]192.168.0.x[/u] or 192.168.1.x. Be aware that this might create [b]routing conflicts[/b] if you connect to the VPN server from public locations such as internet cafes that use the same subnet.[/list] Possibly you are having a conflict ..

Hi, thanks for your answer. But i have only connected from networks with different range... Maybe I will change my local ip-range for the future. But I think the main problem is the DNS Server... A friend of mine has the exact same problem. If he redirects the whole traffic it works. On his notebook it also works without redirecting, same as mine. Regards

As far as I can tell your VPN is working correctly .. please try to explain the problem only.

Hi! I want to use the VPN Connection to stream for example music with my smartphone from the NAS and also use it as a cloud. But i don't want to tunnel all the traffic! Only the data between my NAS and my Smartphone. The rest shouldnt go over the VPN. If i use my notebook it is no problem. I can use the bigger speed from university internet for example and stream from my NAS at the same time. Kind Regards Wuerzminister

[quote="Wuerzminister"]i don't want to tunnel all the traffic! Only the data between my NAS and my Smartphone[/quote]disable redirect-gateway for your phone .. then can you ping your NAS from your phone over the vpn ?

Hi! I have disabled it right now. I can ping my NAS and use it, also my router. I can also ping 8.8.8.8. But i can not browse because of an DNS failure. Maybe an android specific unsolvable problem (without root?). When i traceroute after the 4th station there is no answer (Mobile Network). If i enable the redirect and use traceroute i can clearly see that the traffic goes over my router at home (also Mobile Network). Kind Regards!

If you can ping 8.8.8.8 (google DNS) from your phone while connected to your VPN then you can use it for DNS. What you actually want is only to use your VPN for access to your private LAN while elsewhere. This is the HOWTO you need to read: [url=http://openvpn.net/index.php/open-source/documentation/howto.html#scope]HOWTO: Expanding the scope of the VPN to include additional machines[/url]

I can't get it working :( It should work already with the standard config from my NAS i think. I assume thats an android problem. On my notebook it is working... But thanks for your answers! Kind Regards!

Take your VPN out of the equation .. Can you browse the internet on your phone without the VPN ? What DNS server does your phone have without the VPN active ?

Sure - i can browse without the vpn 8-) When i am connected with the mobile network the DNS server from my Provider. When i am connected with wlan in the university the DNS server from the University. (Same as on the notebook). It does not make any difference if i change it.

My android smartphone can not use the VPN too....

This is not a full qualified domain name and therefore not resolvable by public DNS.
