Talking not for SH5, but in general (I don't know why the OP needs to do so),
I disable my network adapter once in a while just for checking my firewall configuration.

I could unplug the network cable, but that check works only properly if you have just one active adapter.
Having multiple adapters active with different firewall settings for each of them, unplugging the cable doesn't result in a
proper check.
