Recently I've started using Windows 7 at work and I cannot login to my machine anymore from home. The VPN connection settings of my guest computer seems to be correct as my friends can use it to login to their machines. I assume I've to modify some of the firewall rules, but I am not sure which rules should be modified. Any ideas which rules need to be changed?
EDIT: To clarify, the problem is with my machine at work that I want to log into. My other coworkers can log in to their accounts from my laptop, but I can not log into my account from my laptop. However all of my other coworkers have Windows Vista while I have Windows 7. I think I should configure my Windows 7's firewall to let other machines VPN in to it or probably enable the services that are required to let other machines connect to it via VPN. Another problem is that in the firewall config I get this warning box that some settings can be changed using the policies so I cannot modify everything from the firewall settings window.
Thanks in advance.
