I have currently configured a PIX501's ethernet0 to DHCP so it gets an IP from my ISP via a Cable Modem.
ISP --- --> [ethernet0/dhcp] | PIX501 | [ethernet1/192.168.1.2] --> [Layer 3 ethernet1/1 192.168.1.3] | PA-200 | --> Internal network
I need to pass ALL traffic (no filtering) through from the Internet via
Ethernet1 on the PIX.
Ethernet1 will then be connected to a Palo Alto firewall (ethernet1/1) which will perform NAT/filtering etc...
Is this possible?
I think there will be some double-NAT involved here. My understanding is that double-NAT will cause issues if I need to access an internal server.
