Question:
hey folks,
i have a doubt here...once i register my EP server on the internet, can i restrict its access only to the specific users? :
Answer:
What do you want to do ?
Just put your portal in the DMZ ? If you do that, then everyone has to access it via internet. No control possible.
If you access it via another solution - a proxy or what ever - then you have to authorize / authenticate your users there.
good look
