Chapter 5: Setting up the UMTS profile

To ensure that the VPN connection with the network at the headquarters is available on a continuous basis, set both the hold time for the Internet connection and the VPN hold time to '9,999' (keep alive). This is the only way to ensure that access from the headquarters to the UMTS-connected network is possible at all times (e.g. for connecting branches via UMTS where no broadband Internet access is available).

The keep alive function also requires an entry in the polling table. To do this in LANconfig, create the entry for the appropriate connection with up to four IP addresses in the remote network, along with the related ping interval and the number of retries in the configuration area 'Communica- tion' on the 'Remote sites' tab in the 'Polling table'.

If line polling is to be used to monitor the VPN connection, then it also has to be initiated from the VPN gateway with the UMTS/HSPDA card and must be directed towards the remote VPN gateway. The interval times for the polling calls may have to be adjusted depending on the quality of the connection.

Depending on the tariff, always-on Internet connections can give rise to considerable costs, for example with time-based charging. Please ensure that you are familiar with the details of your provider's UMTS tariff.

5.3Other settings

5.3.1Choosing the mobile telephone network

Most mobile data cards are programmed to log in to their own network when coverage is available, and there is no free choice of network.

Once the card is outside of "home network" coverage, there is normally a choice of alternative mobile networks (i.e. roaming, in particular when in another country). Generally speaking, the user now has a choice of network which is to be used for the Internet connection.

In the appropriate UMTS/GPRS profile, set the option for network selection to 'manual'. The entry for the name of the desired network should be the same as that identified by the data card's scanning procedure.
