C1941w and Cisco CP Express Firewall Feature Set

[raulzulueta]

I have a cisco 1941w with ios c1900-universalk9-mz.SPA.150-1.M2.bin and I am using Cisco CP Express GUI. It tells me that the firewall feature set in unavailable. The IOS image in your router does not support the requested feature.

How do I get CP Express to configure the firewall feature?

Your ip nat outside is on the wrong interface. It should be on G0/1, not G0/0.

interface g0/0

no ip nat outside

interface g0/1

no ip nat inside

ip nat outside

HTH,

Yup. That was I.

So I purchasesd the Security license and installed it on the C1941W router. I can now create VPN tunnels. I am trying to use Cisco CPE to configure the firewall. I am getting very erratic behavior. Sometimes the application comes up and most of the time it does not. It also sometimes says I cannot configure the firewall for several reasons. Is there a firewall feature in this router or not. BTW, I am using g0/0 for the WAN and g0/1.10 , g0/1.11 , g0/1.12 for subinterfaces on the LAN. Is that a problem. I am new to this router and its functionality so please be patient with my questions. We can do a webex if that would help more.

Thank you.
