Dual ISP failover Configuration over NAT or other means, Without having to use two ethernet ports
Posted on 2011-09-22
Can the ASA5510 handle Dual ISP`s , ISP 1 as main, ISP2 as Redundant, any other Way than having to use Dual Ports? ,,, ( lots of info online on how to configure this, but you need two ports )
The ASA has 4 ports and 1 management, all 4 ports are used for various Networks -
Outside this is a Switch, ( nothing special or Vlans etc ) with Two ISP connections,
(Think Two ISP DSL routers connected to a switch, which in turn connects to 1 of the Asa ports )
Any way of using NAT or anything else the ASA can do to configure an extra ISP that if the Main isp goes offline, Either NAT or Routing Switchs to the Second ISP.
And what would the Config look like?
Thanks in Advance
