Hi all,

not sure if this is the right place to ask but it looks the best bet i've found so im going to, hope you don't mind.

I am trying to create a lab that includes some cisco devices using GNS3 and to cut a very long story short what im after providing is

a cloud connection using a TAP interface bridged to the internet(br0,eth0,tap0)
2 different B blocks providing connectivity for 3 different networks each (6 in total).

with each of the 3 networks representative of

a home user a soho user a corp user

all routed to the internet cloud using what would be classed as standard, ie.

the home user is connected using DHCP via a DSL connection, the corp user has a number of IP(s) for vlan(s) within it management.

if anyone can point me to some configs or provide some assistance that would be great.

Please provide the following and you will get all help you need,

1. Network topology in a form of visio draw (or anything similar)
2. Details for what you need to design or do

Thanks

C1 is connected to a TAP interface (tap0) tap0 can be bridged with eth0 when full internet access is needed?

R6 is 1 of 2 B block ranges R7 being the other...

N9 would be VM connected to the B block as if using an isp ie. dhcp dns provided by the cloud?

N7 static ip AP + firewall providing dhcp dns to local lan.

N4 corporate border multiply IP routed to N2 (web server) N0 lan server providing dns dhcp etc.. using a switched VLAN for N1 & N3 separation.

R8 was to show that i wanted to include an internal device but im unsure of the placement.

ok so if that sound right wrong or just plain mad let me know. thanks

Actually I liked the idea generally, however I would consider including Linux boxes in the network topology only to play with some quagga features under Linux, or try Win server with routing protocols implementation.

There are unnecessary portions in the design, like the wireless AP and what relates to it, you can basically emulate a switch (layer 2 switch or layer 3 with 16 port module switch).

You can include more than one cloud to separate hosts (created under VirtualBox for example) in different VLANs.

In general, the idea is great, keep up your work and give us the results.

BTW, GNS3 v0.7 has just released, there are some great new feature worth a try, you can even emulate juniper (JUNOS) routers and firewalls.

sounds about right, im using Ubuntu 9.10 and Virtual Box 3.1 is the virtulization platform i am using for this project, i also intend to use turnkeylinux.org appliances for (service) and a custom dynamic dns service for when needs must, but i would still like to include 2 routers within the lab design one owned by the corp and one the v(isp) so to speak.

what kind of configuration would you recommend using the above?

thanks.

It would be nice to play with PPPoE, you can create a server/client using the routers.

Later, you can experiment with different ISP methods for authentication and different ways of providing services, you can use the service redirection to deal with CP (SSG TCP redirection for captive portal like services), or whatever you have in your way.

What I suggest later is try to create some Data-Connectivity models, with different levels of security and technologies, start with GRE, then try IPSec VPN, L2tp, MPLS, and VRF.

Best luck :)
