I work remotely, so I always have to connect to COrporate VPN. I'm having issues with proxy setting that are needed for Force.com IDE. I was able to access Salesforce.com both sandboxes and production from IE, Chrome or firefox, but not able to connect using force.com IDE/Eclipse. I tried to check for proxy settings in Internet Options, but all I can see is "Automatically Detect Settings" is selected and nothing else.
I tried calling my company helpdesk and they are asking me to call either Salesforce/Eclipse teams to find what is wrong with it. :)
So not sure how to get proxy host and port details.
