I am very new in Cisco and hope you could give some advice. Our office uses Cisco 877W via ADSL2+ connection. Wireless, DHCP, firewall are working ok. We have a Windows 2003 Server as a file server. The boss wants to VPN from home to access the files. I have used SDM to try setup VPN then used VPN Client to test from home but it didn't work. My questions are:
1. I believe the 877w router supports Easy VPN server. Do I need to set the Windows 2003 Server as a VPN server?
2. Is there a step-by-step official instruction to do this? I read the manual but I don't know how to customised those instructions for our case.
3. There is a D-link at the other side (i.e. at home). Do I need to set up port-forwarding or anything like that?
