I have wireless hotspot device (Handlink WG-601) which I need to
replace with FreeBSD machine.
The device has following functionality I need to replicate:
1. It has dhcp server (that's easy)
2. It makes NAT between it's "internal" interfaces and "wan"
interface (easy too, but look at 3).
3. It actually responds on every ARP request coming on it's
internal interfaces. That allows it to act
as router for machines that instead of using dhcp are configured
with wrong static IP addresses.
4. It can use RADIUS for authentication of the users.
Actually, non-authenticated users are given IP address (no WPA,
TKIP, etc) and when they first
try to load a web page are redirected to authentication web-page.
Then their username and password
are checked against RADIUS database and only then they are allowed
to connect to the outer network.
Two more things:
1. It was part of a larger wireless hotspot service, sponsored from
the government and implemented by outer organization, so buying
another with my organization's money is out of the question.
2. I'm aware of the issues with security but again I cannot modify
the policy there.
I'll be very thankful for any ideas.
You may look at something like m0n0wall. Running it on a Soerkis box
with wireless should give you exactly what you are looking for. But
even if you can't buy a nice small and cheap box like that, it should
run on anything FreeBSD runs on.
