Windows 2003 RRAS & VPN

I have set up my first VPN server on a windows 2003 RRAS today and it works fine as now. A great improvement to RRAS in Windows 2003 is its built-in basic firewall which blocks every traffic coming from the WAN connection including ICMP requests and exclusions can be defined easily on ICMP traffic, applications and services to let the traffic pass the firewall. Once a client is connected to the VPN server over internet it acts as if it has locally connected to the LAN drop and all resources are accessible normally. Outlook 2003 will download headers on slow connection to retrieve data from Microsoft Exchange on requests. I tried to connect to our servers from the Remote Desktops console and this also worked fine. The PPTP VPN connection is the only concern regarding security so I will work on it to make L2TP work for us.
