I have this PIX501 box and this is what I want to do:
Outside: connect it to a DSL modem (yahoo/ATT SpeedStream 5100). Use DHCP
Inside: connect to one or two PCs. Use static IP. The PIX box's inside IP: 192.168.1.1
The Yahoo's DNS server IP: 192.168.0.1
Could anybody provide a script to make this happen, so that I can run it on the pix.
Long story, short, when first bought it, the Cisco provided some tech support, somehow, they make it working. Now I am out of the support. I made all the reasonable efforts, but still can not make it working (access to the internet), even after I reset it to the factory's default setting.
Here is a list of commands that need to be performed. You man need additional configuration considering that most dsl providers require pppoe user and password setup. I will give you what i have on a pix with a pppoe provider. Its actually fairly simple
You should also realize that your speedstream is natting you once and the pix will nat you again. Sometime you may have a weird issue surfing the net because of the double natting thats taking place. If it happens log into the pix and type clear xlate from priveleged mode. It will clear the existing nat translations .
