Mayak,

This is *great* to know. Thank you for your answer!

So, knowing that it technically will work, I have a few more questions. This is 
more inline to what I really want the network to look like:

The reason the second device is serving as the firewall is that it has much 
higher processing capabilities. The first one is a low powered embedded device. 
Because of where the WAN comes into the house, a high-powered device won't work 
(cooling and noise issues).

So, what I'm essentially proposing is to trunk unfiltered WAN traffic across 
the same wire which has sensitive LAN traffic.

Questions regarding this layout:

1. Is this a security risk?
2. Is there the possibility of bleed-over between VLANs?
3. In this setup, I think that all LAN traffic to LAN Switch A will be routed 
across the Pfsense box labeled A. This is also the box which is routing 
unfiltered internet traffic to Pfsense box B. To me this just feels risky, but 
maybe I'm being paranoid?
4. I assume because of the scenario described in #3, if someone were to 
compromise Pfsense box A, they would then gain access to all traffic bound for 
LAN Switch A, correct? This wouldn't necessarily be the case in a normal 
switched network, right? \
5. Would I be safer, then, to opt to buy managed switches which would be (I 
assume) more difficult to compromise, as it they have much less in terms of 
capabilities at the shell?

Am I over thinking this?

Final question...I have two quad port cards, as I mentioned before. One is an 
HP, which I know supports vlans. The other is an older 10/100 Intel, which I 
can't seem to find the model number. If this device's interfaces show up as 
available under the VLAN tab, does it mean it natively supports vlans? Or, if 
not, how can I verify that it does?

Thanks so much for your patient help.

John

of switches

hi john,

yes, your schema is possible:

- set individual ports to be members of their vlans -- on the right
side, make port 1 member of vlan 10, port 2 member vlan 20, and port 4
of type trunk. same concept on the left -- port 1 member vlan 10, port 2
member vlan 20, port 4 trunk.

the two pfsense connect together using port 4 on a rolled ethernet cable.

all of this accomplished on the `Interfaces -> Assign -> VLANs`

VLAN tag for port 4 would be 1,10,20 (1 is the administrative vlan)

cheers
