6.2 Connection with a single leased link - dial on demand

Figure 6.6

Configuration of interfaces — an on-demand dial link

The Internet interfaces group can include multiple dial-ups. However, only one of these links

can be set for on-demand dialing. If another link is dialed manually, WinRoute will route

packets to the corresponding destination network in accordance with the system routing table

(see also chapter

18.1

) and perform IP address translation (

NAT

). However, such configuration

would be of any use. It is therefore recommended to keep only a single on-demand-dial link

in the Internet interfaces group.

To change the dial-on-demand link, use the corresponding option in the interface edit dialog

(see chapter

5

) or use the context menu (by right-clicking on the link).

Warning

In the Dial on Demand mode, default gateway must NOT be set on any network interface of

the firewall! On-demand dialing is based on absence of the default gateway (if no route exist

in the

routing table

where a

packet

would be directed, WinRoute create a default gateway by

dialing an Internet link).

Dialing options

For dial-ups, the interface settings dialog (see chapter

5

) includes also the Dialing settings tab

where specific parameters for dial-up connections can be set:

Login information

If login data for the particular dial-up connection change, it can be updated here or it is

also possible to use the data saved in the operating system (if saved there).

Time intervals for persistent connection and persistent hang-up

Under certain circumstances it may be needed that dial on demand works only within

a certain time period (typically in working hours) and that the link is hung-up outside

this range. With respect to cost rates of individual providers, it can sometimes be most
