Enable or disable IP header compression in PPP
Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 7
You can use this procedure to enable or disable the IP header compression in Point-to-Point Protocol (PPP) packets sent over dial-up or other slow links.
IP header compression involves negotiation between two computers as to what is compressed and how. It can reduce the size of packets, improving the throughput on a slower communications link.
Any user account can be used to complete this procedure.
To enable or disable IP header compression in PPP
If you want to modify the connection you are currently using, disconnect from the server.
Right-click the connection that you want to modify, and then click Properties.
On the Networking tab, click Internet Protocol Version 4 (TCP/IPv4), and then click Properties.
On the General tab, click Advanced.
Under PPP Link, select or clear the Use IP header compression check box.
IP header compression is not a configurable option for IPv6.
For more information on IP header compression, see RFC 2507 and RFC 3544. (http://go.microsoft.com/fwlink/?LinkID=121).
