Do duo authentication over a proxy



I have some VMs on the intranet that don’t have connection to internet. Is there a way that duo authentication request can be forwarded to a proxy server that has connection to the internet


You may want to setup that Internet facing server and configure pam_duo.conf to use it.

http_proxy Optional
Use the specified HTTP proxy. If the HTTP proxy requires authentication, include the credentials in the proxy URL. Example format: http_proxy=
