IPCop - Windows Network

[closerwalk]

Here we go... Thanks in advance for all your expertise.

Here is what I want to do is implement IpCop 1.4.6 with Cop+ and some addons in my current network configuration.

The IPCop Firewall
It is installed on a intel 933 512MB memory 7 GB hard drive system. Running great.

Heres the design of the current system and the desired system. Can anyone tell me the correct approach?


OUR CURRENT CONFIG
T1 - WAN 20X.X.X.X
|
SONICWALL TZ-170 FIREWALL 10.0.0.3
|
WINDOWS SERVER 10.0.0.10 ---
|
Managed Switch
| |
CURRENT NETWORK CURRENTLY FED BY SERVER FOR DHCP.


DESIRED CONFIG
T1 - WAN 20X.X.X.X
|
SONICWALL TZ-170 FIREWALL 10.0.0.3
|
IPCop Firewall 10.0.0.11 GREEN
|
WINDOWS SERVER 10.0.0.10
|
Managed Switch
| |
NETWORK USERS (Need to DHCP Feed From Server)

Basically I don't want to disturbed the current config I just want to add features of IPCop, dansguardian and etc...

Please accept my appologies if this is off topic.
