Double nat & dhcp

[Nas.CloudBusinessPortal]

I’ve searched a bit last night, but…

So I’m asking.

Is there any way to set up a double nat, each router with its own dhcp server.

Maybe I’m not looking at the answer the right way.

Trying to make a second network to go through the first.

Yes. Put one router behind the other.

Umm what about the dhcp server.

Well, not both of them respond to a request on the network?

Both both devices into router mode. Each non their own subnet. Plug a ethernet cable from the wan port of the second router to a LAN port of the first router.

No, because you would have two different networks (e.g. 192.168.1.x and 192.168.2.x), each with their own DHCP server.

But that is what I would like.

So I can also have another list of static ip addresses too

There you go then. Easy.

But won’t wolf routers respond to a request for a DHCP?

I’m thinking about the device that is behind the second router, the first router will see the request and they’re both going to respond with a lease.

 

[ColinTaylor]

No, because they're two different networks. DHCP only operates within it's local network. It doesn't extend to other networks.

 

[Jeffrey Young]

Ok, so you got curious with the static list comment. What is it that you are trying to accomplish?

Remember, in this setup, router 2 will be able to talk to clients on router 1, but router 1 will not be able to talk to clients on router 2 unless you turn off the firewall on router 2 and setup a static route on router 1.

If you have no need for the clients to talk with each other, no problem.

DHCP is broadcast and will not traverse a router without a special helper statement (which will not be in place on the Asus LAN to WAN).

As long as you don't connect the LANs together they will be isolated from a DHCP standpoint.
