First time setup of PIX 515e, Please help!

[netman8762]

Hi I am setting up a PIX515e firewall and cannot get it to work properly. We just want to start with a basic setup. The IP internal network is 172.18.1.xxx and the internet connection it though Verizon DSL and a small Netgear router. The router IP is 172.18.1.1 and the server is at 172.18.1.20, the server gives out the DHCP. The DHCP range is 172.18.1.100-125. I just want to get this setup so that we have our traffic going through the PIX and then the Netgear to the internet, is that the correct way? Also would like a DMZ but once the traffice is routing properly I am sure we can get that. This PIX was previously used in a different setting so the system was "clear config all"d and it is a blank slate.

Any help would be greatly appreciated!

Thanks in advance!

Hi,

You can find all and other detail information here

http://www.cisco.com/pcgi-bin/Support/browse/psp_view.pl?p=Hardware:PIX&s=Software_Configuration#Software_Samples_and_Tips

Basically all you need is the following

ip address assignment

default route

nat and global

e.g.

ip add outside 10.10.10.10 255.255.255.0

ip add inside 20.20.20.20 255.0.0.0

route 0 0 outside 10.10.10.20

nat (inside) 1 0 0

global (outside) 1 interface

then you can build up complex configuration on top of this

Thanks
