We have a cisco router that has a public IP address on the outside interface. the inside interface needs to pass traffic to a Cisco PIX firewall maintained by the customer.
The customer wants to us our network as a second route to the Internet by assigning IP address that connects to our Cisco router.
Their PIX has a primary Internet connection via another provider.
We can get to the Internet via our router, however, the PIX is not passing traffic to and from the customer PIX.
Does anyone have the necessary configs? Is this a NAT issue? If this is a NAT issue, can anyone provide me with the proper configs?
