getting Internet connection for my lab

Hello experts,

I created an isolated LAN. I have windows server 2012 domain controller and workstation  that is joined to domain.The Ip I assigned for testing this network is to The switch I am using cisco 3500.

I want Internet access on my workstation  and domain controller. I have Internet modem connected to my wireless modem for my home computers. The IP assigned here is to 254.

Please let me know how I can connect my Internet to the new LAN. Thank u

You can set up a router to connect the two networks.  The LAN side of the router should be an unused valid IP address on the 10. network that you created.  The default gateway on the domain controller and the workstation should point to that.  Connect a cable from your switch to one of the LAN ports on the router.

The WAN (internet) side of the router should have an unused valid IP address on the 192. network (or use DHCP to assign one).  Connect a cable from the WAN port of the router to a LAN port on your wireless modem/router.

You could skip the router altogether if you had two network cards on the domain controller, but that will not be as isolated.

My switch is C3550 and is a layer 3 also. Is there a procedure you can recommend for me ?

Right now the gateway on the domain controller and workstation is pointed to the switch VLAN 1 SVI in the 10. 0.0.1

I am also thinking of getting router C1800 but what will be the steps to configure it besides putting ip address on the interfaces LAN1 and LAN2.

Thank you.

The other part of the configuration would be to ensure that traffic between the different interfaces of the router is allowed.

Not really want I am looking for but yes I will put a router.
Can you be a bit clearer on what you are actually looking for?

An inexpensive router will do the trick.  I don't know enough about the C3550 switch to know if/how this would be done through it.

I believe that you'll need some sort of router (either a physical router or using the server to do the routing through a second network card) to accomplish what you want.

Does your existing internet router allow multiple subnets?  If so, that could do the trick.
