           Hi X-quisite
              *First of all let me ask you some questions. Are you now able to connect to PIX CLI via telnet?
              *Is there a NAT or PAT configured?
              *Can you post running config here?

Regards

Mr Husy,

I can connect to the pix CLI via Telnet
No PAT or NAT is configured, actually nothing is configured, still at factory default.
What do you mean by “running config” ? Sorry to sound stupid?

        When you type sh run, your running config of PIX appear but no use if it is at factory default.
         Following link will guide you through some basics. Please ask if you dont understand steps.

Mr Hussy,

Thank you for the link.
There two interfaces on the PIX
1)If my internal network ip Range is 192.168.0.0 should i configure the interbal interface to have a static IP address of say 192.168.0.1

2) What should i configure the external interface to be?
I have static WAN IP Adress from my ISP
Also i am using an ethernet modem which has an IP address of 192.168.1.1 and configured as bridged, with a DHCP server.

What i am confused about is should i configure the static WAN IP address on the external interface or an static IP address of say 192.168..1.2 which is of the same range of the ethernet modem?

          Hi Nazmul
           1) Yes, you should assign a static IP address for inside interface of PIX. 192.168.1.1 is the default one.
           2)If your global IP address is assigned to your ethernet modem, and you reach internet with 192.168.1.1 gateway, then you should assign an ip to your outside interface in this network. If this global IP is by a router or other ISP device, then you should assign that ip to the outside interface of your PIX.
