PIX 501 Newbie setup issues

cygnusguy — Fri, 21 Feb 2020 07:59:49 GMT

Hi.

I am new to PIX and am having some setup issues.

I have just purchased a PIX 501 - unlimited license. My internal network is currently configured using static IP's using 192.168.12.XXX with a 255.255.255.0 subnet.

I want to replace my current firewall with the PIX due to a customer request to set up a VPN tunnel. (I don't even want to go there, yet.) I can't seem to change the PIX internal IP address from the default and get it to work.

I keep getting "...DHCP Range not on the same subnet" errors. I cannot use DHCP in this application due to other program requirements.

How can I get this to work. I have successfully hit the internet using the default config, so I have my DNS setup correctly. What am I missing here??

Hi,

Try this:

clear dhcpd

no dhcpd enable

interface eth1 auto

ip address inside 192.168.12.254 255.255.255.0

nat (inside) 1 0 0

global (outside) 1 interface

clear xlate

clear local-host

Make sure you have a PC on the inside with the correct DNS settings and with default gateway of 192.168.12.254, then try to go to the internet, it should work. Let me know

Thanks for the help. I found out where my issue was. I cleared dhcpd and was able to change my internal IP, but it still wouldn't communicate. When I ran a show config, I noticed that the http address was not reflecting the new IP. I changed that to the new ip/subnet and now it's working.
