[NoCat] NoCatAuth across a LAN/WAN

[Emilio Recio]

I have just configured and set up NoCatAuth with the two server, 
separate networks, NAT, DHCP, caching named, and MySQL Auth 
configuration ... i am guessing it's a pretty standard out of the box 
config. One NIC is for the external, and one is for the wireless. The 
wireless NIC is attached to a simple Linksys router.

This is just for proof of concept and prettying it up for my bosses. 
Eventually, this is going to be a similar setup except, that we are 
going to be using Cisco Aironet 1200's serving multiple SSID's. One of 
those SSID's is going to be for our "public" wireless network and the 
VLAN associated with it is going to be trunked, and routed, all the way 
to the gateway's "internal" interface several blocks away before being 
dumped out onto the Internet.

In looking at the nocat.log files on both servers I noticed that there 
were references to MAC addresses while doing authentication. If 
dhcp-helper is configured at the routers and the APs are all on the same 
VLAN, is there anything special I would need to think about before using 
NoCatAuth? Does anyone already have a similar setup to this in 
operation? Are there any tips you might recommend based on some caveats 
and gotchas with the increased complexity?

Thanks in advance,
