If you look at the RIAA/MPAA lawsuits that eventually boiled down to  
an open access point - those people got off (mostly) but they had to  
sustain huge expensive court battles and the burden of proof was on  
them to prove that it wasn't their activity but an unknown user of  
their access point.

That was music and movies - child porn is a whole different topic and  
I doubt the authorities are willing to entertain the "it wasn't me"  
argument.

Since most law enforcement or D.A.'s know very little about how the  
Internet works - it is almost impossible to have them believe that  
even though it looked like you, smelled like you and sounded like you  
(your IP, your equipment, your Internet billing account) it wasn't you.

Your ISP will give you up in a second -the last telco I worked for  
would treat lawfirm issued letters (C&D, request for IP or customer  
record, etc) the same as a court issued subpoena, request for evidence  
or DCMA.

Legal advice aside - if you resubnet another router behind your  
network and only offer one route (egress to the cloud) your probably  
OK but your safety is only as good as your device security. If you can  
control the management interface of that router from your personal  
subnet and obscure it from the community segment, your probably OK.

Are you planning on trying to manage QoS or are you just hoping they  
don't seed a bunch of torrents and run a tor exit node? ;)

Aside from the possibility that sharing your internet connection may  
be a
violation of your ISP service agreement, the question I would ask is  
if
you'd be liable for any potentially illegal activity that may take  
place on
your connection.

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.
