ok, you need to create 8 vlans, the first 7 are for what you have mentioned above, also dont forget to create the interface vlan x, interface y etc, and then assign it an ip address from the subnet, this will be the clients default gateway address.

Next, create the 8th vlan, vlan 200 or whatever, and give it an ip address of your choosing or from the default subnet that is assigned to the adsl router, say for example the adsl router has a default ethernet address of 192.168.1.1 then you could creat vlan 200 (vlan number can by anything) and assign it ip address 192.168.1.254, then configure the adsl router with the static routes to route to your interlan vlans (1-7) via the vlan ip address.

Finally on the switch, enable ip routing, and ceate a default static route 0.0.0.0 0.0.0.0 192.168.1.1 (or whatever address the adsl ethernet has)

That should be you!

HTH,

PS. Dont forget to config DNS server on clients or they wont be able to browse.

Hi

can you revert back on the router model you are using out there ?

Ideally you can terminated all the VLAN's onto the router and create subinterfaces for each respective VLAN's.

Once you are done up with that you can have PAT configured on your router with overload onto your WAN interface which will be your outside interface.

Dear Spremkumar

thank you for the POST but i want to tell you somthing! im not a pro in VLAN and Cisco Devices, after 21 days i will take a CCNA Course to improve my self in that subject.
