Dear group members,

In the network environment which I maintain,  we have a video streaming
signal piping from my station, to Los Angeles using a direct IPLC line
of 45 Mbps.  Once reach Los Angeles it was pipe to another equipment
which present the video signal to various recipient.

Once I tried to have a internet connection by subcribing an E1 line to
the ISP provider in Los Angeles.  I got 32 Public IP and quiet happy
with the service.  In Los Angeles, I have 1 unit of Cisco 7513 with a
DS3 card.  I got another Cisco 7513 in Malaysia with a DS3 card.

To make the internet connection work, I subscribed an E1 link with the
local ISP in Los Angeles.  I bought a Cisco 3640 with E1 port. I use
the FE port on Cisco 3640 to tap to the Cisco 7513.

Over in Malaysia, I bought a cisco 2811 and tapped from a FE port to
Cisco 7513 FE port.  Then I created a tunnel between cisco 3640 and
cisco 2811.  Below is the sketch diagram.

                    |----------Los Angeles------------------|
   |---------------Malaysia---------------|

ISP -----E1------Cisco3640 -----FE-----Cisco7513
===T3==Cisco7513------FE----Cisco2811

<============================================>
                                                          Tunnel

In this tunnel I put in a public IP and I manage to get internet.

I got one of my office friend who wants a 256K for his personal
emailing system.  Using the current E1 subcription, I planned to give
him 1 public IP and tap his computer to a Cisco Catalyst 3750 port and
rate limit it to 256K.

The question or challenge for discussion here is can I do tunnelling on
Cisco 3750.

What other options that I have to play since I only have Cisco Catalyst
3750 to play with, I do not intend to buy any more since this is more
on exploration work.  Hard for me to justify to the company since I
cannot create a busines impact from the exploration work.

Regards

Iskandar Hussein
Malaysia.
