    Hello,

    I am running a cisco 3620 router connected to a Alcatel speedtouch pro ADSL modem(running in bridging mode), the Cisco is taking care of the internet connection using PPPOE on one of the ethernet interfaces.

    A LAN is running on the second interface and there is a dialer interface for the DSL connection.

    What I am trying to do is work out how to setup a web/mail server on the private LAN with a private address and have this server available for people on the internet.

    I thought I figured it out but when I try and access the web server by either the FQDN or via the actual ip address it doesnt work.

    I would also like to know how to get the router to automatically update Zoneedit when there is an ip address change detected on th dialer interface if this can be done.

    Any help you gurus can give would be greatly appreciated as my head has a huge bruise on it from banging it against the router.
