Cisco ASA adding another interface
Hi Guys
I have two ISPS that come into the building and I have a Cisco ASA 5510 with two spare interfaces. One of those interfaces is connected to one of my ISPS, can i setup one of the other interfaces to use the new ISP?
And do I have to make sure the new ISP router is in bridged mode?
Thanks a million

the 255.255.255.255 is for a host. What you need is the subnet mask for the gateway of the 2 host network that your ISP segregates it's and your internet connection routers (usually a /28).
MAke sure you have a sec plus licence! (show version)

So that means that the subnet mask is 240?
I have tried that and I am getting "ip address not valid" ?

Thanks for the grade. Good luck.
This method would help you fail over to your secondary ISP if primary ISP interface physically goes down .
