Linux requires a script to change DNS servers.

Then add this to your client config:

Code: Select all

script-security 2
up /etc/openvpn/update-resolv-conf.sh
down  /etc/openvpn/update-resolv-conf.sh
The script should already be present, if not you can find it here:
https://github.com/alfredopalhares/open ... esolv-conf

As for accessing the internet over the VPN, we cannot help you with that,
please contact your service provider.

Hi TinCanTech
many tks for your answer

I'm runing openvpn in openwrt

That script runs in openwrt?
best regards

My tun0 interface

Type: Ethernet Adapter
Device: tun0
Connected: yes
MAC: 00:00:00:00:00:00
RX: 0 B (0 Pkts.)
TX: 27.92 KB (112 Pkts.)

tun0
Protocol: Unmanaged
Uptime: 0h 0m 10s
MAC: 00:00:00:00:00:00
RX: 0 B (0 Pkts.)
TX: 27.92 KB (112 Pkts.)

It sends but is not receiving (even with or without your proposed changes)

best regards
