Answer:
I haven't seen
cisco configuration professional but since its gui based I'm sure you could
find your way around or go through a setup procedure? Here is a tutorial i
found which may help - the wizard should be able to take you through the whole
setup.

Anyway - just
incase you are interested in CLI...
There might be
a couple of things you have missed here, like DHCP for your LAN and NAT for
outbound traffic. So I will assume you need this in the configuration below
If this is a
static address assigned by your ISP then you can do this:
ip name-server
202.153.32.2
ip name-server
202.153.32.3
!
interface fa4
ip address
172.16.26.130 255.255.0.0
no shut
!
ip route 0.0.0 .0
0.0.0.0 172.16.62.1
If you want to
configure your LAN for example on fa1 you can do this:
interface fa1
ip address
192.168.1.1 255.255.255.0
no shut
To configure
DHCP for your clients to connect you can do this:
ip dhcp pool
INSIDE
network
192.168.1.0 255.255.255.0
default-router
192.168.1.1
dns-server
202.153.32.2 202.153.32.3
To configure
NAT using PAT (port address translation you can do this)
access-list 1
permit 192.168.1.0 0.0.0 .255
!
ip nat inside
source list 1 interface fa4 overload
!
interface fa1
description INSIDE
ip nat inside
!
interface fa4
description
OUTSIDE
ip nat WS-C3750X-12S-S outside
