Hi,
I run pfSense on a few ALIX boxes, usually as tunnel end and as access
point. When I can plug one of these machines into any (wired) network,
I
have easy access to my home network through the private WLAN the ALIX
provides.
This works beautifully.
I travel a lot and today hotels only provide WLAN access. Ethernet
ports in
hotel rooms are relics of the past.
I solved this problem by using a Mac to connect to the Hotel WLAN and
then
select "Share my Intenet (WLAN) connection to Ethernet" in the
"Sharing"
control panel. When I then connect the ALIX WAN interface to my Mac
using a
cable, things again work nicely, but I effectively block a Mac as
router
that I would rather carry around.
My thought was "throw a second ALIX box at the problem and make that
one
connect as client to the hotel's WLAN", then plug the two ALIX's
together
with a short cable.
I did try this, hacking the hotel's WLAN details into the WLAN
interface
configuration of the second ALIX (configured to use "Infrastructure"
mode,
of course), but the WLAN interface always stays down, no matter what I
try.
My hope was that the the hotel's captive portal mechanism could be
fooled to
give access to my client ALIX from any client computer connected to AP
provided by ALIX number 1, but as the client ALIX's WLAN is always
down, I
didn't even make it to this point.
Did anyone here successfully do this (and share some insights)?
Definitely doable. I've done it in about every combination imaginable.
ALIX or similar hardware with a wifi card, a pfSense VM on a laptop
with a LTE card via USB passthrough, same for wifi USB. Ethernet
bridged to a VM on a laptop. Some ugly combinations of those where
multiple layers of NAT were necessary before the traffic left my
equipment, but was fine as a temporary hack.
For connecting to captive portal networks, everything behind it will
look like one device as far as their network is concerned, as you're
NATing everything to the same source IP and MAC.
How do you have the wireless interface configured for standard and
channel? What wireless card are you using?
Sorry for the delayed response. Currently traveling.
I'm using a Compex WLM54SAG23 miniPCI card (cf:
http://www.pcengines.ch/wlm54sag23.htm). Uses an Atheros AR5414. pfSense
is v2.2.1 if I remember correctly.
Best,
Ray
