Viscosity VPN to Netgear Nighthawk 7900

I have followed the detailed instructions from the KB article on setting up a Netgear Router with Viscosity. The only instruction that I was unable to do was turning on NAT in the Internet Setup section. That is no longer available. Needless to say, I can't seem to get Viscosity to work with my Netgear Router.

This is the error message in my log file: Options error: The command "dhcp-option" or one of its parameters is invalid for this version of OpenVPN (2.4.4). Please edit the connection, make sure the command is valid, and try again.

Hi sduttonusa,

The command "dhcp-option DNS 8.8.8.8 8.8.4.4" is invalid. The dhcp-option command should only have a single DNS server listed at a time, to have more than one server set multiple copies of the command should be used, e.g.:
Code: Select all
dhcp-option DNS 8.8.8.8
dhcp-option DNS 8.8.4.4
If Netgear's configuration generation has automatically added the incorrect command I recommend getting in touch with their support staff to report a bug. If you've added the command remove it, and then follow the steps here to list the correct DNS server/s to use:

Hi James,

Thank you so much for your help . . . that was it. I removed one of the DNS servers and it works just fine now. I didn't add the second DNS. It was put there from the router's generated file.
