"All in one" box possible?

Hi,

I'm trying to build a solution for my testlab with the following option:
- run as a WLAN client to the outside
- run WLAN AP on the inside
- hide nat outgoing traffic
- span (mirror this traffic to a wired interface)
(troughput speed is not an issue)

(e.g. running a network 192.168.1.0/24 on the inside on WLAN and 2 wired ports, and span the traffic to the 3rd wired port. The second WLAN miniPCI card should connect to the internet, a hotel hostspot for example)


My understanding right now, this should be possible. A routerboard 433, equipped with 2 x miniPCI WLAN cards should do this, or am i wrong?

thanks,
Wolfgang

Yep, you're right. 433 is perfect for that. If you need more ports - 493 then.

Great!
Can someone confirm that i"m able to mirror traffic from the two WLAN ports and one wired port to a single wired port?
Or are they some restrictions?
Thanks!

Hmm, does anyone know whether one can mirror traffic from a miniPCI WLAN card to one of the wired ports on a RB433?
I have not found a description for this, just for mirroring a wired port.
Thanks, Wolfgang

What do you mean by "mirroring"? Normally everything is possible

Mirroring (or span) -> duplicating the traffic from one ( or more ) interface to another (e.g. to analyse the traffic)

It is not possible to mirror traffic from Wlan port to ethernet port. You can mirror traffic between switch chip:

If you are routing or bridging traffic from Wlan interface to ethernet interface of the switch chip, you can mirror this traffic to another ethernet interface.

Can't you use CALEA? It will mirror all traffic to another RouterOS machine (CALEA server):

Use TZSP format - for reception with Wireshark.
