Connecting 3 devices to the internet

Cisco / Catalyst 2960g 7port

Specs: Windows XP

We have a very small separated network, it's
basically a blade system and 2 workstations
that are working together (processing images).

The 3 systems are connected to a Cisco
Catalyst 2960G 7 port switch.

We have to connect them to the internet, and I
don't know how to do it. I can't log in to the
2960g, we inherited the system and I don't
even know the switch password (I've never
used cisco before :-\ ). We have a spare
internet connection now, and we want to
provide internet access to these 3 systems.

The router is a Thomson 585i, we used it
before to provide internet acces to the other
lan. The router has the ip address
(it was the gateway before), and also was the
DHCP server to provide local IP addresses to
the LAN computers.

The 2 workstation have the
and IP addresses and the
gateway is, I guess the
gateway is the DHCP server right?. How do I
have to configure the router to connect it to the
switch and provide internet access to the 3

Thanks for reading it !

You need to figure out what's what with your network and let us know.

Do you presently have a network that is connected to the internet? If yes, we need details. What subnet is it using? Does it have a SOHO Router connecting it to the internet? If yes, what make/model and what is it's IP configuration.

Does the Cisco switch have an IP? If yes, what is it?

Can you get the switch login info from whoever configured it?

If the router you mentioned has 4 LAN ports, you could plug your 3 clients into the LAN ports on it after getting it connected to the internet. This would furnish internet to the clients.

Thank you very much Curt,

Finally I managed to get it working. I had to phone to the person who installed the separated LAN and he gave me the information. I had to disable DHCP in the router and change the LAN IP adress to a different subnet, then I just connected it to the switch and "volia", all 3 computers had intenet access. The blade system provided the DHCP service.

Now I have to set up a VPN for remote access to the server... OMG

Thanks again !
