Hello,
I hope you can support or guide me if what I intend to do is possible:
I have a web server with the external ip 187.210.xx.xxx and with the mapped ip 172.16.x.xx, as a VIP, I just hired another ISP, and I want to publish this same server with that external ip so that when my main ISP My server is not working, exit through my secondary ISP.

first of all, Thanks.

Q; Are you doing BGP ?

Q; is the 187.210.x.x/xx advertised to both ISP?

if you answer yes to both then set the vip interface to ANY

config firewall vip edit "VIP-ANY1" set mappedip "172.16.1.1" set extintf "any" next end

Then run a "diag debug flow" against the target and monitor.

I do not use bgp, my web server is published only by my main ISP which is 187.210.xx / xx, my intention is to publish it in my second ISP but I do not know how to do it, this in order that when my main ISP fails my secondary ISP take your place automatically so as not to lose the published service,

That would be impossible if your 2nd ISP does not originate the prefix. You could publish 2x VIP one with x.x.x.x -map-to-server and y.y.y.y-map-to-server for the webservice services.
