PfSense chaining (sort of)

[VMax]

Hi,

I'm running a ESXi server with currently one pfSense install. It's configured with the DNS server, DHCP server and Squid running in transparant proxy mode.

I'm thinking of solving the transparant proxy / traffic shaping problems with chaining 2 pfSense installs, the scheme would look something like this:

WWW    ->    pfSense QoS      -> pfSense Squid/DNS/DHCP      ->    LAN

pfSense Qos WAN : PPPoE
pfsense Qos LAN : 192.168.1.3

pfsense Squid WAN: 192.168.1.2 DG: 192.168.1.3
pfsense Squid LAN: 192.168.1. (DG for my clients)

Would this work? These addresses are examples, but would it work in this configuration?
Should I configure my clients with DG .3 or .1 ?

Thanks for helping me out!
