Yes, in our setup, we use Layer3 at ISP level, and we have a lot of CPE
routers doing NAT.

With NAT, chilli only sees one client. This has practical uses if you want
several users sharing the same internet account




David Bird Said: 

Of course, even layer3 mode means you can not Nat everyone to the same IP.

Could use layer3 mode or have the Cisco router bridge the traffic layer2. If
layer3, you can also use a different dhcp server.

Hi Russell,


>From what I've seen on the diagram, I seriously doubt that it will work,
because even the DHCP leases are relayed properly, the router in performing
NAT, meaning that CoovaChilli will only see the MAC of the router, while all
the rest is behind it, invisible to CoovaChilli.

Dear David. B & List Greetings,


i could not conclude how CoovaChilli can work in this environment, i require
little help to understand. some of you perhaps already using. my setup (LAN
Diagram) is attached to the mail.



Would user get the login page? 

I seems that if one user would login everyone has access due to NAT on cisco
