BR500 Mac VPN problem with Big Sur

My office has a br500 vpn router, and all the macs at home connect to it to do work. With big Sur, we are not able to connect any longer. The client software Netgear recomends - tunnelblick - no long...

I had the same issue after upgrade to Big Sur. Vpn to my nighthawk stopped working.

TAP mode is not supported anymore. (https://tunnelblick.net/cKextLoadError.html)

Solution using tunnelblick (or VIscosity):

Download "for non-windows" from Netgear advance seutp->VPN Service

Edit the. xxxx. conf file change the line starting with "remote" to "TUN" port (ip and port available in in Netgear advance seutp->VPN Service->tun mode service port)

Change "dev tap" to "dev tun"

Save

Add .tblk to the downloaded folder.

Drag to Tunnelblick (or import to Viscosity VPN)

Connect from Big Sur should now work.

I tried what you said but am getting an error. 

 

The OpenVPN log contains the following message:

"Unrecognized option or missing or extra parameter(s)".

This error means that an option that is contained in the OpenVPN configuration file or was "pushed" by the OpenVPN server:

     • has been misspelled,

     • has missing or extra arguments, or

     • is not implemented by the version of OpenVPN which is being used for this configuration. It may be a new option that is not implemented in an old version of OpenVPN, or an old option that has been removed in a new version of OpenVPN. You can choose what version of OpenVPN to use with this configuration in the "Settings" tab of the "Configurations" panel of Tunnelblick's "VPN Details" window.

See the VPN log in the "Log" tab of the "Configurations" panel of Tunnelblick's "VPN Details" window for details.

    Hi 

    Sorry to hear that your config does not work.

    Client side I am using Tunnelblick 3.8.5beta01 (build 5610) (or Viscosity which imports settings from Tunnelblick)

     

    Here is my  .conf (which works from Big Sur), maybe that could be helpful

    Replace the "nnn.nnn.nnn.nnn" with router IP and "mmmm" with portnumber of the TUN

     

     
    client
    dev tun
    proto udp
    remote nnn.nnn.nnn.nnn mmmm
    resolv-retry infinite
    nobind
    persist-key
    persist-tun
    ca ca.crt
    cert client.crt
    key client.key
    cipher AES-128-CBC
    comp-lzo
    verb 5
