Connecting: Wait TapEmulator

Post by juanjo.s2 »

Hi,

I'm using a vpn profile with tap device which is working seamesly on a Raspberry PI 3B, but with VPN Client Pro it connects but it stucks on "Connecting: Wait TapEmulator".

On the openvpn server I can see the device is connected but I don't receive any traffic of other devices on the network.

Please, can you post the VPN log?

Here the steps to get the log:
  • tap on VPN profile name
  • tap on LOG tab
  • tap on top right icon with 3 dots
  • tap on "Export log"

This happens because the client cannot obtain a ip address from the DHCP server.
Please, try to set the ip address manually.
Here the steps:
  • edit the VPN profile
  • tap on "Options"
  • select "Set IPv4 address" and fill the below fields

I'm not using ip addresses on the tap connection, are they mandatory?

yes, it's mandatory.
The ip address can be assigned manually or with a DHCP server
