C2K internet connection

[Bill Bixby]

Anyone know if it's possible to share the C2K internet connection they provide with the gateway 10.51.232.1 amongst vlans on a legacy network?

I don't see why not, they would need to add your routers ip or mac address to their allowed list. Most board schools legacy machines our routed through c2k for their internet anyway.

Bill are you trying to setup a dual wan router/modem.

We were looking at setting up vlans in here so we could control our networked devices easier, but weve put it on hold for a while as we don't have the time to sit down and properly think it out.

We were going to set ours up like this:

Vlan1: Servers
Vlan2: Domain PC's
Vlan3: Printers
Vlan4: iPads
Vlan5: Staff Devices
Vlan6: Guest access(internet only)

The problem is getting them to talk to each other, its a lot of frigging about to get it setup right and we didn't have time, i think that will be a next summer job.

I'm trying to set up two separate subnets but both using the one internet connection.  I created two vlans that replicate between switches over the trunk ports and all communication between them are fine.

I had the ethernet cable plugged into a port on switch 3, a layer 3 switch.  I turned on routing abilities on the switch, turned the port off as a switchport that the internet cable was connected to and gave it the address 10.51.232.2 (to keep it in the same subnet as the 10.51.232.1 connection) and set it as the default route for any addresses that couldn't be found on the network.  My two subnets were 10.51.0.x and 10.51.8.x

Host -----> Switch 3 --trunk----> Switch 1 (that has the internet connection) ------>out routed port --->C2K router

I think were I have gone wrong is that there is no route back from the C2k router into the network

I think I would have needed a router in between C2K's router and capable of doing NAT.

Bill, what kind of switch are you using?

[Bill Bixby]

Cisco 3550, does routing but not NAT
