I have a 2611 Router at home that i use to access my isp the 2 ethernet ports are configured with private ip addresses Ethernet 0 192.168.0.1, Ethernet 0/1 10.0.0.1 Both ports have a static/default route pointing to dialer interface also both interfaces have dynamic nat overloading applied,i have a Pix 501 that i would like to use but i am unsure how to configure it with this setup,would i have to disable nat on the pix. any advice would be greatfully appreciated.
Hi .. if you are trying to use the PIX instead of the router then the only issue is that the PIX 501 will only give you 1 internal subnet as it does not support more than 2 segments ( outside / inside )
You could connected then as below ..
Internet->Firewall->Router ( Lan 1 and Lan 2)
The default gateway for the router will be the internal interface of the PIX. The Default gateway of the PIX will be your ISP. And the PIX can be configured as PPPoE client. as per the below link
