I would like to request a feature enhancement on Wireshark: in
the Interfaces dialog, could you allow selection of multiple
interfaces, so that we can scan more than one at the same time,
inside a single viewing window?
Particularly on a firewall or router, there is often a situation
like a spoof where you are not sure exactly which interface is
involved, and you need to scan more than one at the same time. I
know you can start multiple instances of Wireshark, but this
becomes very very inconvenient when needing to observe more than
about three interfaces at the same time.
It's a common request and is #2 in the Capturing section of the WishList:

It's already supported on Linux which has the "any" pseudo-capturing-device.
