Create a text file and save it as proxy.conf in the following location:
C:\Documents and Settings\<username> in Windows.
/home/<username> in Linux.
$home/ in Macintosh.
Specify the IP address and the port number of the forward proxy in the following format:
proxyHost=<IPaddress>:<port number>
For example: proxyHost=172.10.0.0:8080
(Optional) If the Basic authentication method is used for the forward proxy, SSL VPN can connect in Kiosk mode as well as Enterprise mode. To enable SSL VPN connection when authentication is enabled, specify the username and password of the forward proxy administrator in the following format:
proxyAuth=<username>:<password>
This is not a recommended method because you need to specify the credentials of the forward proxy in the configuration file and this might be a security vulnerability.
Save and close the file.
