Well, it makes some sort of sense for me (but as I'm no expert, could be a sweet dream :) ) so it's best I try to share what I'm looking for : There are 2 level of firewalls : 1st with fw1 & fw2 protects from internet and manages DMZ 2nd with ifw1 & ifw2 manages inter-vlan filtering I'd like to achive high availability accross these 2 levels, without the need for a switch between, hence the four red cables. To be precise, it's also because I want to be able to unplug ifw1 (which leads ifw2 to take over) without having fw2 taking over fw1 (which would be the case if I'd only have one nic toward the inside on fw1) . Therefore, if you unplug the link between ifw1 and fw1 (pcn2), pcn3 on fw1 should be elected as master and talk to the new master on the other side. So, have I changed your mind about it ?
