Client can't go to Internet in 2 PIX config..

Hi,

I'm trying to connect a client to the Internet using a 2 firewall scenario. I have an Internet FW and a DB Firewall with a WebServer in between. Right now, I want the clients on the inside of the DB FW to connect all the way to the Internet. What syntax/entries do I need on one/both of the Firewalls in order to make this happen? or if this is possible at all. Any suggestions are welcome.

Internet <-- Internet Router <-- Internet FW <-- Switch <-- WebServer <-- Switch <-- DB Firewall <-- Client

Internet Firewall

ip address outside 208.205.172.2 255.255.255.0

ip address inside 192.168.3.1 255.255.255.0

DB Firewall

ip address outside 192.168.8.1 255.255.255.0

ip address inside 192.168.2.1 255.255.255.0

WebServer (has 2 NICs)

Outside NIC 192.168.3.39

Inside NIC 192.168.8.39

TIA

Tom

Hi!

Couple of questions:

1) Is the WebServer able to ping 192.168.3.1?

2) Is the DB firewall able to ping the ip 192.168.3.1?

3) Is the WebServer doing the routing?

If all is yes, then do this:

Internet Firewall:

nat (inside) 1 0 0

global (outside) 1 interface

DB Firewall:

nat (inside) 1 0 0

global (outside) 1 interface

If all connectivity is working fine this should do the trick, just make sure you have the proper DNS settings on your PCs behind the DB firewall.
