Pfsense setup

[nPhuzion]

hi guys i have a network setup just would like comments and recommendations  it goes like this

1 DUAL CORE XEON 3.0
4 GB RAM
3 SAS 70 GB
2  GB NICS

I install server 2008 setup AD and DNS, all clients connect working fine,
The net comes in on one NIC the other feeds local lan
pfsense 1.2.3 setup as firewall /gateway and also handles dhcp. Pfsense VM bridges to the two nics  with snort, squid and squid guard to keep things clean
PPTP vpn for some remote stuff

thats basically it all comments and ideas welcome
