Internet Redundancy

I am running HSRP between two Internet routers, both are connected to different ISP's.

Behind these routers I have a Cisco PIX, where I have natted my private IP to a Public IP of specific ISP (of range 203.197.x.x.).

How can I acheive internet redundancy in this scenarion????

My other ISP IP range is 125.18.x.x.

Re: Internet Redundancy

You would need to do the NAT on the routers. You could also use GLBP to load balance between the two.

Please rate helpful posts.

Re: Internet Redundancy

In addition to information provided by previous poster, you may look into well known link redundant/bakup dual ISP through backup interface, although this architecture does not privides load balancing you may still achive inbound traffic through backup isp link via two nat statemets, you would need atleast pix code 7.x as this feature was introduced in code 7.

Personaly I would prefer load balancing, and nat at the router like previous poster said, but it all depends what your requirements are and where all your NAT statements configurations reside and how many they currenly are in your PIX. If you are looking for just backup ISP then look into backup interface and dual ISP in PIX/ASA.

Re: Internet Redundancy

As I am running a VPN over the primary ISP I would not able to load balance. Further the point where I like the nat to happen is @ my PIX.
