ASA 5520 with failover NAT with TWO ISP

[shasun]

Hi Friends,

Currently we have one ISP1 and all traffic goes to this way. Suppose our isp1 goes down, our outside user cant get the server. All servers are nated to this ISP1.

We planned to purchase a another ISP2. Shall we Configure same inside server to map this ISP2? so that one primary ISP1 goes down it will take place the outside trafficISP2. is this possible? pls guide me

Hi Thiru,

You can definitely configure dual ISP on your firewall. When the primary ISP goes down, the firewall would automatically failover to the secondary ISP link, therefore causing no disruption to your server access, follow this doc:

Hope this helps.
