Hey John,

You might want to take a look at DD-WRT, it has built in facilities for this, some of them ad-supported earning you 
some cash as well, if you want to go that route.  It also has isolation for that access point built right in.  Since 
you're talking about running two AP's simultainously my recommendation is that, with both of them running DD-WRT, you 
have one in the 'hot spot' mode and handing out it's own addresses on a different RFC1918 address range while the 
private router has the port your public AP is plugged into setup as 'isolated.'  Another option, if your modem signs 
into the internet (opposed to your router doing) you can put a switch in front of the routers (or if your modem is one 
of those horrific all-in-one wireless router with X ports on the back).  If your network supports this then this would 
be the most secure way to go, and potentially the easiest to setup.  You could also look into the La Fonera project...

I hope this makes sense, I'm dead tired...if it doesn't or you have any questions I should be more awake in the morning 
and would be more then happy to help.

Hello,

I have a home wireless network that I’d like to make available to neighbors
who need to borrow a connection from time to time.  Consider it karmic
repayment for the times I’ve had to borrow someone else’s open connection.
Of course, I’d like to do it securely, so I’m looking for some advice.

My main network has a wireless router connected to the Internet, with a few
wired connections to my home computers.  The main router’s wireless network
is protected by WPA, access control via MAC address, etc.  My thought is I
would attach a second wireless router (Netgear) to a port off the main
router and leave it unsecured, using a second subnet, and block any routing
between the two subnets, other than straight out to the Internet, but I’m
not sure the best way to do that.

So, a few questions:

If I set up a second router with a subnet “subservient” to my main router,
presumably it has to get an IP address within the address space of the main
network, but how can I limit access to that network to only my Internet
interface?

Would it make more sense for my secure network to be subservient to the main
network, i.e. open up the main network and secure a secondary subnet off it?

I also have a Secure Computing SG 300 Firewall/VPN appliance, could I
configure that help keep the networks separate and my home network secure?
It’s got a lot of nice features, but I’m not sure it would help make my
configuration more secure.

This may be a very bad idea, so I’d also be happy to hear why that’s so if
it’s true.

Thanks for any advice.
