I just want to know this is possible so I do not waste my time searching for a solution. Our office has a Cisco 871 router. We have several employees who remotely access the office from their Windows XP computers. Is it possible to establish an IPSec tunnel between the remote Windows XP computers and the Cisco router? I'm really just interested in a yes or no, but if someone could point me to some tutorials, that would be helpful as well. Thanks.
