Hi, I have one cisco router and there are two different ISP links is configured on router interface e0 and e1, and s1 serial port is directly connected with outside interface of pix firewall.
Ip address e0 126.96.36.199/24 (Public Range)
Ip address e1 192.168.10.1/24 (Public Range)
Ip address s1 10.0.0.1/24 (Private Ip)
Inside Network 172.16.0.1/24
Outside Interface 10.0.0.2/24
Now my question is, which of the commands we need to set on router to pass the traffic and fireall. I want my both links to be alive and when anyone link get down then traffic by default go from the other link and what would be Nat command cenario on router and firewall. Please send me full configuration, if possible.
