sorry if this question may have been already asked but I can't find a simple answer for this specific question:
how to configure a second external interface, with a second ISP, in order to route the Internet traffic/NAT to one or the other depending on policies?
In my case I have to change the ISP and since I can't just switch it off, I have to start moving some services to the new ISP.
For example make a subnet going to the Internet with the 2nd ISP, move a published service to the new public IPs, etc.
My first attempt was to configure the secondary external cluster interfaces and add the new router's IP in the Gaia's Default route (added to the primary, with priority "none"), but it didn't work.
I know about PBR, but I see that they have critical limitations (no IPS, no URL filtering.. practically unuseful!)
So, what is the simple solution for using a second ISP, which every other brand supports?
