You need not explicitly define these parameters, however. The following information is provided asreference to the possible router configurations advanced users may desire.The IP router interface on the WAN link: may be numbered or unnumbered. may or may not use Network Address Translation (NAT). will attempt to autoconfigure itself without an explicitly configured connection profile, if permitted to do soby the setting of the Must Match a Defined Profile item in the Default Profile screen. See “The defaultprofile” on page 8-20.The link up process at the interface between the WAN data link encapsulation module and the IP routerfunctions as follows: When the WAN data link comes up, the router will search for a configured connection profile that specifiesWAN encapsulation. If more than one WAN profile exists, the router will use the first such profile. If no WAN profile exists, and the Must Match a Defined Profile field in the Default WAN Profile is set to No,the router will construct a Default Profile, and the link up process will continue using this constructedprofile as if it were an explicitly configured one. If no WAN profile exists, and the Must Match a Defined Profile field in the Default WAN Profile is set to Yes,IP will not come up on the WAN link. The router will log an “IP connection refused” event in the WAN EventHistory. If a WAN profile exists (or a default one has been constructed), the router will attempt to configure itsinterface on the WAN link using the information stored in the profile.CCCCoooonnnnnnnneeeeccccttttiiiioooonnnn PPPPrrrrooooffffiiiilllleeeessssSince you will probably only have a single connection to your ISP over the WAN link, you may not need to createmultiple connection profiles. Multiple connection profiles are useful on leased (unswitched) interfaces only tosupport meshed WAN connections. If you do not intend to set up meshed WAN connections, you do not need tocreate multiple connection profiles.Connection profiles may be used to define the connection information for your WAN Auxiliary Port access.Connection profiles define the line and networking protocols necessary for the router to make a remoteconnection. A connection profile is like an address book entry describing how the router is to get to a remotesite, or how to recognize and authenticate a remote user dialing in to the router. For example, to create a newConnection Profile, you navigate to the WAN Configuration screen from the Main Menu, and select AddConnection Profile.
