Secure Networks

Hello Experts,

I have 2 Linksys routers. 192.168.1.1 network and 192.168.2.1 network, both with a 255.255.255.0 subnet mask. I also, have a DSL modem with 1 Public static IP address and the modem only has 1 LAN port.

I want both networks to have Internet access, BUT I don't want the computers on the 2 different networks to communicate with each other in ANY way, so its completely secure. I am looking for physical configuration and logical setup within router.

TIA

PS: I don't mind purchase other hardware if necessary, so long as it doesn't cost too much :)

You need a Router in front of them. and basically set one up as internal and one up as DMZ. on the router.
or set up VLan's on the router.

Is there a away to put one Linksys in front and the other behind it without the need for a third router?

You can, but the network on the "behind" router will have access to the network in "front".

So there would be a one way communication only?

There is no way of the "behind" router to ONLY have internet access and not be able to even see or communicate with the "front" router?

---->I also, have a DSL modem with 1 Public static IP address and the modem only has 1 LAN port.

do you have access to the DSL modem and does it have routing capabilities?

if so, you could do this with a managed switch.

create 2 vlans one for each network and place one network port (port connected to one linksys) in one vlan and the other network port in the other vlan.

connect the DSL router to the switch and trunk the port.

The other option would be to purchase a layer 3 switch and do the same steps as above but on the switch create a default route pointing at the DSL modem for it's next hop.
