Hi,
authentication using a Web page is possible when you have used Client
Authentication. The user connects to the Firewall, authenticates, and
then his IP address is able to use the services accepted by a rule like

users@InternalNet   Internet  anyService   ClientAuth ...

For the authentication is a direct connection to the Firewall necessary,
so you will have to accept this before your Stealth rule - or, you put
the rule for authentication before this rule.
The connection is (using default ports) to port 900/tcp. But you can
change this by editing $FWDIR/conf/fwauthd.conf to any other port you
want. Just find the line

900     fwssd       in.ahclientd    wait    900

and customize the port. Connecting the configured port with http will
not require a separate Web server, but has to be accepted by the
Firewall. The pages can be customized by editing the HTML-files at
$FWDIR/conf/ahclientd. Be careful not to "destroy" the forms.
It's necessary to define the users in the user manager. First, define a
template and then each user. They can also be imported, if you have
exported them before (fwm dbexport / fwm dbimport).
If you want to use HTTPS/SSL for authentication, please have a look at

Hope it helps,
best regards,
Matthias

  I'm replacing the hardware running FW-1 NG FP2 using
SecurePlatform.  I've got the software installed on the
new hardware, but I've hit a snag duplicating part of
the existing configuration.  (Basic spec:  Users should
not notice any change when the switch is made.)

  We have one subnet whose users must authenticate against
the firewall before they are allowed to connect out to the
Internet.  With the old hardware in place, they can use a
shortcut to get to a login web page hosted on the firewall.
With the new hardware in place, this never connects and
eventually times out.

  Which isn't entirely surprising.  At very least, I need
to somehow recreate the user/password list on the new box.
I don't know if I also need to do something to install/run
a web server on the box, and/or make sure it will accept
connections.
  I don't know how to do any of this.  (Well, I have installed
and configured Apache before, but I don't know if that's even
necessary in this scenario....)
