How secure is ifconfig eth0 down ?

Say I want to have a PC w/ 2 ethernet cards (eth0 and eth1) and only want one active at a time. Each NIC would be attached to different networks acting as a suspense bridge (PC gets data from eth0, then disconnects and connects to eth1 and transmits the data). This is kind of an odd idea, but one I'm toying around with. How secure would this connection be? The command to do this would be:

ifconfig eth0 down

Would anyone from the network attached to eth0 then be able to access anything on my suspense PC?

Hi,

Once you set the command ifconfig eth0 down all traffic is inhibited. How secure do you think that is?

No response from/too the eth0 device.

The only thing more secure would be pulling the cable.

I'd guess the only way that this would *not* work would be if your 'suspense machine' were already rooted, and altered specifically so that the command would return success without actually doing anything. That is possible, of course, but I'd guess highly unlikely.
