Web Setup Projects allow you to create executable Setup.exe files and Windows Installer packages (MSI files) that administrators can use to easily deploy your applications to a web server. The Copy Web tool can synchronize a website between a remote server and your local computer. This is useful if you want to do deployment and testing on your local computer and then upload the website to a remote web server. The Copy Web tool can also be useful in environments with multiple developers because it detects versioning conflicts. Precompiling a website removes the delay that occurs when ASP.NET compiles an application after the first user request. To precompile a website, use the Publish Web Site tool.

To be reachable, the VPN server must be assigned a public IP address to which packets are forwarded by the routing infrastructure of the Internet. If you have been assigned a static public IP address from an ISP or an Internet registry, reachability is typically not an issue. In some configurations, the VPN server is actually configured with a private IP address and has a published static IP address by which it is known on the Internet. A device between the Internet and the VPN server translates the published and actual IP addresses of the VPN server in packets to and from the VPN server. This device is known as a network address translator (NAT), and typically these devices are either routers or firewalls that are NAT capable. NAT Traversal (NAT-T) and L2TP/IPSec Previously when using L2TP/IPSec, there was an issue with going across NAT boundaries because IPSec, which maintains the encrypted tunnel for the com munications, could not negotiate security associations (SAs) across NAT devices. This issue has been resolved by Microsoft with the implementation of NAT traversal (NAT-T). NAT-T allows Internet Key Exchange (IKE), the nego tiation protocol of IPSec, to negotiate security associations (SAs) across NATs. NAT-T is a feature of Windows Server 2003, and you can add NAT-T to all cli ent operating systems in one of the following ways:
