Citrix Access Gateway CSR creation is done through the 'Certificate Request Generator' of the 'Administration Tool.'
1. In the 'Administration Tool,' select the 'Access Gateway Cluster' tab and then open the window for the appliance.
2. In the 'Certificate Signing Request' tab, enter your company's information as requested.
The 'Access Gateway FQDN' field should be the fully-qualified domain name through which your server is accessed externally, or should begin with an * if you are creating a request for a WildCard.
The password that you specify will be the password for your private key.
3. Clicking 'Generate Request' will generate the CSR file, which is saved to your Citrix Access Gateway as an encoded text document.
You will need to open this file as a text file and copy the entire body of it (including the Begin and End Certificate Request tags) into the online order process when prompted.
