I think I am on the right track but unsure. Again, I am running PIX 506 (only 2 interfaces-stuck with 5.1(2) software) on a small network.
Here is what I am trying to achieve:
1) Allow unrestricted internet access from the inside interface.
2) Allow incoming connections to my web server.
Here is what I have so far:
PIX Version 5.1(2)

Sorry, I didn't get into managed firewall appliances until about a week ago and I am in my 40's so things don't sink in quite as well as they did when I was in my 20's...

No, not you, it seemed like everything I said was just getting repeated.
Anyway, it's cool, we're all here just trying to help.

Which, by the way, I do not take for granted and I appreciate more than I can say...
03-22-2007 01:32 PM
Ok, as abinjola and I were trying to say, there are a few things you need to figure out. The most major of which I would say is where do you want to NAT?
03-22-2007 01:33 PM
do you have the router access,? so that we check if the router is configured for natting
I hope i am making sense that the router needs to further PAT or NAT the traffic (to a public ip )coming out of the firewall private outside IP
the fw config looks good..

This is 1 solution, like I was trying to say before...but requires 2 more public ip addresses.

Yes I do. Prior to purchasing this firewall, the ISP's router was configured to port forward requests to the appropriate server...
port 80: to 192.168.254.20 (web server)
port 25: to 192.168.254.50 (email server)
