#3735 — bridging hotel WLAN

FromLaszlo Lebrun <lazlo.lebrun@googlemail.com>
Date2016-05-10 11:10 +0200
Subjectbridging hotel WLAN
Message-ID<ngs8kq$e5o$1@tota-refugium.de>
Hi experts,

is it a way of bridging a hotel WLAN?
The WLAN is open and has a browser-based login.

I tried to bridge the WLAN and RJ45 on Windows 10, but that was not 
working
Indeed a soon as I plug the RJ45, the wireless connection is suspended.
How can I prevent that?
Would I have bettre chances on Linux?

Is the bridging of a hotel WLAN even doable, or is the browser 
autentication process actively preventing bridging anyhow?

Soory for my Noob question, I'd appreciate any light in that topic that 
I don't know yet.
Thank you.

Let me try to understand. You want to "share" the internet connection
that the computer obtains from the wifi via the RJ45 connector so that
you can connect other devices?

I have not done this in a long time, but it was what we did long ago
with telephone modems and computers, and it was called "sharing the
network connection" if I remember correctly. I suppose that it is doable
in Windows (but I don't remember how), as it is in Linux.

Basically, your computer acts as a router, with NAT and Masquerading.
Let's say that your computer gets an IP on the WiFi, say 192.168.1.35.
The computer would create another interface for the cable on
192.168.10.1, for instance, and would be responsible for giving machines
connected to it another IP in the 192.168.10.* range, and it would be
responsible for routing the packets from and to both interfaces.

It would really help if you told us what it was you were trying to do.
What it sounds like is you are connecting via wireless, and then you are
plugging in your cable, and your computer is getting a cable address and
rerouting everything to the cable. But why you would be plugging in both
is unclear. So, pls say what you hope to accomplish and what you are
doing to accomplish that, rather than telling us that your solution to
an unkown problem does not work.

I am sorry having been unclear.
Yes the "ISP" is a hotel WLAN. It provides an "open" WLAN, which 
however requires a sign-in over the browser. I am not allowed to sign 
in with another device :-( unless I stop the first sign-in.
I would love to be able to bridge the released internet connection to a 
separate private WLAN router over RJ45 to feed my other devices.
Currently the OS is Windows10 (cough), I was experimenting at that 
level. I could also dedicate a Raspberry PI to this job.

It boils down to a very common setup which doesn't have anything
to do with hotels or WLANs.

                G
   world --- gateway --- your other devices
                 <----- your network ----->

It's just the situation with a LAN with private addresses, and one
special host in that network which also has internet access.

1. Set up a local network (say, 192.168.42.0/24) for your computers.
   This won't have anything to do with the WLAN, or the internet at
   large.

2. Make all of them understand that G is their gateway out from the
   local network.  Perhaps DHCP can tell them that (I don't use it
   myself) but you can always configure a gateway manually.

3. In G, you want to enable IP forwarding and NAT[0].  The Linux
   command I seem to use for that is

   iptables -t nat -A POSTROUTING -o eth0 -s 192.168.42.0/24 -j MASQUERADE

   I suppose you'd have to replace "eth0" with the network interface
   facing the internet.

I also suppose Windows can do those things, if that's more convenient
for you.

/Jorgen

[0] Meaning roughly "If a packet A->B enters me, and A is on the LAN
    and B is on the internet, I will change the packet to say G->B
    (G is my world-facing address) and forward it.  And I will do the
    reverse for packets B->G.  That way, I will never mention show the
    address A to the world at large, which wouldn't know what to do with
    it anyway, since A is a local address."

You don't want to bridge them.
Instead you want to bring up your ethernet port as another network
(with private addresses e.g. in 192.168.73.xx handed out by a dhcp
server running on your machine), and setup NAT forwarding so as to hide
this private network from the hotel network (so it all appears as
a single host from the hotel's point of view, which is one of thethings
their authentication process enforces).

Yep!
How would the easiest process to achieve this look on a Raspberry Pi?

Finally i have bought e TP-Link WISP&3G router. It was a breeze to 
setup and I have an own local network as well.

Of course this may lead to a problem of a double layer of NAT. The
router will do NAT on all the guys beyond the router, and then your
computer hooked up to the hotel will do NAT again. I guess you can also
put your own computer behind the router, and use the router to hook up
the hotel .

That is exactly what I did.
The WISP router is the sole contact to the hotel Wifi. All my devices 
are linked to the router. Any device can provide the authentication 
procedure and, once done, the others get access as well.

No. Bridging of a wireless interface in managed (infrastructure, i.e.
associated to an access point) or ad hoc mode has been disabled in
recent kernel because it is not reliable.

Furthermore, VirtualBox can't bridge to a wireless interface either.
I think of it as a bit of extra security for my XP VM.  :-)

OK, but it's not forbidden to discuss alternatives...
By the way the TP-Link is very probably built on Linux.

Of course :-)

But what you are doing is not bridging, that's not the name of the
thing. In Windows parlance it is called "sharing the internet
connection", if I remember correctly. In Linux, masquerading/forwarding/nat.

Yes, of course.

The OP asked a question which was left unanswered so far, and I just
gave an answer for completeness which may be useful for other readers.

Sorry, but I don't understand. The OP was not really talking of
"bridging", he confused the name.

How do you know ?
The OP obviously wanted to do "connection sharing", and there are two
usual ways to achieve it : bridging or routing (+masquerading). So what
makes you think that he was not really trying to use bridging ?

You call that bridging? I call bridging an interface to add another
logical interface to the same physical interface. Like having eth1 and
eth2 on the same socket.

The term was used by the OP without knowing the difference between
layer 2 and layer 3 connections. This is a common misconception.

Bridging is layer 2 connection, meaning that usually Ethernet frames
are forwarded between interfaces. This is what the Ethernet switches do.

Routing is layer 3 connection, meaning that IP packets are forwarded.

There is a thchnical difficulty to include a WLAN interface to a
bridge, as the interface must be in promiscuous receive mode to be
able to get frames destined to the other side of the bridge, and
WLAN protocols complicate the process.
