http://www.yourictmagazine.com/techonology/tips-a-tricks/206-basic-to-configure-a-cisco-router-to-connect-to-internet-

the link above configures the router to access internet.
I wonder if this router is connected to T1 line or to a ADSL router.(it seems like it's a connection to T1 line)
I have seen configurations where they use Dialer interface, I believe that 's when they connect the router to  a ADSL in order to provide internet for users in the LAN.

My Goal is to ask an expert out there to paste the configurations used in both case.
Case1--Connecting LAN --->Cisco Router--->ADSL
Case2--Connecting LAN---->Cisco Router--->T1

Thanks

All you need is a default route to the external IP address of your provider.  Or you can use a default route to your external interface.  Example:

interface se0/0
ip address 68.25.11.1 255.255.255.252
<--other options in interface may be here

**Your ISP next hop may be 68.25.11.2

Then you could use either of the following commands:

ip route 0.0.0.0 0.0.0.0 68.25.11.2
or
ip route 0.0.0.0 0.0.0.0 int se0/0

Then, you can configure your clients to default gateway to the internal IP address of your router.  If you want, you can use DHCP to provide all client IP information or statically configure (DHCP is preferred method).  

As far as DNS is concerned, you can either use the router as a DNS server or have one locally that points to your ISP's DNS Servers.  Either way, your clients will need DNS to access Internet resources by name.

Any further questions, please let me know.

Can you write an explanation under each line of the configuration.
Some words are common in most of the configurations, but some they are like unheard of, for instance vpdn,request dial-in, etc.....

I would appreciate it if you write an explanation under each line of the configuration.

Is the for a lab (for personal educational value and not for Q/A or pre-production testing) or does it offer value to a production environment.  The reason why I ask is that, while we like to everyone, it does take away time from those who need a fix pretty quick, or are under the gun to get a project out the door.  No offense meant, just asking.
