Connecting 2 WAN clouds on the same IP address range.

Hello, I have a problem connecting my office to two third party companies.

I have two Cisco 1700 series WAN links to my office from these companies, Both routers are fully managed by their respective companies, both use static routing, and both are using the IP address range.

The first company assigned my office the address range

The second company assigned my office the address range

My office can be set to any IP address range.

My questions are:

Is it possible to have a connection from my office to both networks at the same time? If so how?

Do I require these companies to provide me with their static routing information? or can I use routing protocols?

Do I need to perform NAT?

Can I use a PIX 515e firewall with three interfaces?

Sample configuration would be greatly appreciated


Re: Connecting 2 WAN clouds on the same IP address range.

It's possible to have connections to your offices at the same time with the usage of subinterfaces.The usage of static and dynamic protocols depends totally based on the size of the topology of your network.If it's a very very small network static routing will do. Performing a nat totally depends upon ypur decision whether to use a public ip or not.If required you can use a pix firewall
