IP security is provided in a virtual private network using network address translation (NAT) by performing one or a combination of the four types of VPN NAT, including VPN NAT type 'a source-outbound' IP NAT, VPN NAT type 'b destination-outbound, VPN NAT type &#x2018;c inbound-source' IP NAT, and VPN NAT type &#x2018;d inbound-destination&#x2019; IP NAT. This involves dynamically generating NAT rules and associating them with the manual or dynamically generated (IKE) Security Associations, before beginning IP security that uses the Security Associations. Then, as IP Sec is performed on outbound and inbound datagrams, the NAT function is also performed.

A graphical user interface includes a buddy dialog which dynamically becomes part of a current dialog upon selection of a selectable object on a property page. A unique buddy dialog format is provided for each of a plurality of data formats for selectable options, or objects, displayed on the property page. The user may see the values for each of several associated options by clicking (or otherwise selecting) on each option successively. Each time an option is selected, its data values appear in its corresponding buddy dialog without popping up another dialog.
