hi guys
am trying to setup ISA 2006 enterprise as a gateway to the internet and as a firewall.
the connection to the inernet is throu an ADSL Modem connected to the usb port on the ISA server.
i've installed the driver for the adsl modem and created a dialup connection for the internet under Control Panel > Network Connections
when i manually connect to the internet it works fine but then the internet is not shared.
Now 2 things i want ISA to do.
1: i want ISA to connect to the internet automatically everytime windows start up without having to login first to Initiate the connection.
2: i want ISA to share the internet.

what i've done so far after i installed ISA is that i created some firewall rules to allow certian traffic to go out from the internal network to the external such as http,https,ftp,ping,dns and so on.
under the ISA management tool i clicked on Arrays>[Servername]>Configuration>General>Specify Dial-up preferences and ticked the box on Allow automatic dialing to this network and then selected [External]
and another tick on configure this dial-up connection as the default gateway.
on the same page there is an option that says Use the following dial-up connection so i selected the internet dialup connection that i created.
but ISA still doesn't connect automatically
in terms of sharing the internet does that have to be done through RRAS.

i realy appreciate your help
