Thanks all for the info.
Baring in mind the e-mail you've sent I've scaled down the m0n0wall installation
from Quad cards to Dual cards. (Partly because our hardware supplier delivered
dual cards by mistake, might be a good thing).
12 Interfaces are enough for the moment.
The ISCSI data will be diverted through a seperate switch so the traffic on the
m0n0wall won't be that severe. This way I hope to have my m0n0wall up and running
with better performance.
