I have been given a public ip's with subnet /29 by the isp with a speed 30Mb/s. I want to configure a network with router and two firewalls which has to be placed in two different floors. And also i have to divide the speed of 30Mb/s equally i,e.15 Mb/s between two floors.how can it be done?

Hello,

Hello,

with two firewalls (and assuming these are ASA firewalls) you could do a High Availability setup. Public IP addresses would be configured on the outside interfaces of both firewalls.

The document below describes how to set up the ASA failover:

Hi,

Hi,

Please confirm.

1. Does 1.x.x.240/29 was given to you by your ISP for your internal network use only? There is a separate subnet between your ISP and your Router.

2. Do you need one-to-one NAT (also known as Static NAT) now or in future to a host behind your Firewall1 and Firewall2? Web/Mail server.
