Pix Problems, need some guidance

Im setting up a PIX 506 firewall, i havent done much firewall stuff so i need a little help.

Currently i have my workstation directly connected to the pix. I can ping the inside interface fine.

The pix is then directly connected to a Cisco router, which is connected to another Cisco router, when then connects to the internet, the routers have full connectivity. From the pix i can ping all router interfaces, all remote sites, basically everything. However when i try to connect to the internet from my computer it fails and i cant ping any further that the PIXs inside interface from my machine.

Here is the PIX config:

One thing that i dont understand, do i need to configure NAT at all? we have NAT configured on the router.

Im sure there is some configurations that im missing but i just need some guidance.... thanks!

Configure NAT from the inside out.

eg.

NAT (INSIDE) 1 10.1.19.0 255.255.255.0
GLOBAL (OUTSIDE) 1 Interface

This sets up PAT using the PIX's outside IP. A pix won't route traffic so much as translate it between interfaces.

Also whats the default gateway on your PC?

I'm not sure about the 506, but I've had some some PIX firewalls that won't work well with private IP's on the external (outside) interface.

If your outside interface is using private (192.168, 10.0 or 172.16-31) try taking the 2 routers out of the picture and let your PIX use the public IP from the ISP on it's outside interface and see if it works.

PIX does not differentiate between what is a "private" IP and what is a "public" IP....it doesn't care. It's all in the configuration. If it ain't working, it's configured wrong.

I agree- a PIX does exactly what its told. It may take a few trial runs and PIX versions to get it right though.
