Hello, 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 outside

Hope this helps

Hi,

I am having a similar issue. The wan IP of the ISP is 111.93.***.*** /30. The gateway is 111.93.***.***. There are are six usable LAN ips starting from 111.93.245.144/29. The primary DNS is 103.8.46.5 and the secondary DNS is 103.8.44.5. I have configured the WAN ip on the WAN port FE 4. But when I tried to configure one of the lan ips on FE 0 port. it says IP address cannot be configured on the Fast ethernet switch ports. So I created a Vlan and assigned that Vlan to FE 0. After that I connecte that port to the pc, But the internet is not up. Please help to fnish this configuration. the LAN ips are required for me for various applications.
