Hi Everybody !

I have some trouble to make AirVPN worked on Ethernet LAN NIC while it works on WiFi NIC. My Laptop (W10 64 bit Pro) have 2 NICs :

LAN (Ethernet 1 Gigabit) : Realtek PCIe GBE Family Controller - DHCP auto IP and DNS

WiFi  :  Qualcomm Atheros AR9485WB-EG Wireless Network Adapter - DHCP auto IP and DNS

TAP : TAP-Windows Adapter V9

My ISP : Orange (FR) FTTH 100 Mbps

My client : airvpn W10 64bit portable, protocol UDP 443

Test 1 : trying to connect on recommended server with LAN NIC


As you can see in the log, it doesn't work.

Test 2 : trying to connect on recommended server with WiFi NIC


On WiFi it works.

I think it's TAP NIC that screw up when i use Ethernet Cable on LAN NIC. Of course I uninstall my TAP and reinstall it, but it still doesn't work. I reseted W10 tcp ip stack but it changes nothing (by following https://community.openvpn.net/openvpn/wiki/reset-network-tcp-ip-stack).

I have no idea what's happening.
Ask me if you need more infos / log etc.




EDIT 1 : in the log, we see "Le nom distant n'a pas pu être résolu ......... " (i.e The remote name could not be resolved ...) but my DNS are OK.

Please feel free to disable IPv6 and also try the Beta client.

Make sure your DNS are set to automatic in your LAN adapter.

My NICs are on DHCP (so it's automatic) for IP and DNS configuration. IPv6 is disabled on all NICs.


Edit 1 : I disabled all my Firewall and any kind of protection, I dowloaded Experimental Client Eddie, with default client configuration it doesn't work.


Edit 2 : I disabled DNS Switch Mode, it works


-> Conclusion : it's a DNS forcing issue


Edit 3 : is this a problem ? what is DNS Switch Mode ?


On ipleak.net, I can see that my DNS is the AIR server
