IPSecVPN MOST Configuration Service Provider

4/8/2010

By default, when there is a Mobile VPN connection, the Connection Manager blocks all traffic except Internet Key Exchange version 2 (RFC 3406) on the real interfaces on the device (for example, Wi-Fi and GPRS). Mobile operator service traffic (MOST) lets users access services offered by mobile operators outside of the Mobile VPN connection while VPN is being used.

The IPSecVPN MOST Configuration Service Provider lets you configure the MOST IP addresses and hostnames. Typically the OEM includes the mobile operator's MOST rules (hostnames and IP addresses) on a commercialized device. The mobile operator can then use this configuration service provider to update the rules through provisioning.

The following table shows the default security settings for the IPSecVPN Configuration Service Provider. The default security role maps to each subnode unless specific permission is granted to the subnode.

To help protect devices, make sure to read the Security Considerations below.

Parameters

• IPSecVPN
  The root node of the IPSecVPN object. The default security role maps to each subnode unless specific permission is granted to the subnode.

  Data type	Node
  Roles allowed to query setting	Manager
  Access Type	Get
  Occurs	One
  Scope	Permanent

• IPSecVPN/MOST
  The MOST subnode of the IPSecVPN root node. This characteristic is used for the MOST rules. Using the metabase and the mobile operator certificate on the device, Windows Mobile assures that only the mobile operator can gain access to the MOST.

  Data type	Node
  Roles allowed to query setting	Operator
  Access Type	Get
  Occurs	One
  Scope	Permanent

• IPSecVPN/MOST/Service<#>
  A service to be allowed under MOST.

  Data type	node
  Roles allowed to query setting	operator
  Access Type	Get/Add/Replace/Delete
  Occurs	Zero or more
  Scope	Dynamic

• IPSecVPN/MOST/Service<#>/URL<#>
  The hostname or IP address associated with the corresponding mobile operator services.

  Data type	chr
  Roles allowed to query setting	operator
  Access Type	Get/Add/Replace/Delete
  Occurs	Zero or more
  Scope	Dynamic

Remarks

Mobile operator services are identified by the servers that provide them, and each server is identified either by its hostname or its IP address. The VPN architecture ensures transparent passage of traffic to and from these hostnames and IP addresses.

In the IPSecVPN MOST Configuration Service Provider, the MOST characteristic is used for the MOST rules.

A service is identified by using the SERVICE<#> characteristic. For example, SERVICE1. For each service, URL<#> tags specify the IP addresses and hostnames associated with the service.

The corresponding value attribute will be a hostname or IP address. The maximum number of URLs for all services together is 100.

Security Considerations

To allow only the OEM and mobile operator to configure MOST settings, you should do the following:

• If you will manage the MOST settings over OMA Client Provisioning, make sure that you preconfigure the OMA Client Provisioning Server on the device. For information about how to do this, see Bootstrapping To Use an OMA Client Provisioning Server.
• If you will manage MOST settings over OMA DM, make sure that you preconfigure the ROLE parameter in the OMA DM account bootstrap message that is handled by the DMS Configuration Service Provider. Configure the ROLE parameter to a value of 152 (SECROLE_TPS + SECROLE_MANAGER + SECROLE_USER_AUTH).
• If you will manage the MOST settings over both OMA Client Provisioning and OMA DM, then both sets of comments above are applicable.
