I'm planning on getting two new Palo Alto firewalls for setting up IPSec tunnels. I think the first tunnel will be a primary tunnel and the second tunnel will be back up. I'm tempted to set up my new firewalls as active/passive HA, to make life easy. But to be sure, please could someone suggest what are the advantages of using active/passive compared to active/active for dual IPSec tunnels?
I'm going to be using BGP over the IPSec tunnels and BGP to the LAN, so if I go for the active/passive option, it just means i dont have to double up my BGP peers...
Any links to the best practices for BGP and IPSec HA would be appreciated... thanks
I would say it doesnt matter with regards to a VPN tunnel. I think you have to choose if you actually require an A/A HA scenario. If you can get away with a A/P HA, I would say do that.
Agreed with @OtakarKlier; in your situation it doesn't matter if you deploy A/P or A/A as far as the VPN tunnels go, makes no change to how you are going to do things really. There aren't a lot of use cases where I would really recommend an Active/Active Palo Alto deployment to be honest, there are far too many issues that are present in A/A deployments.
Thank you people,
I think I will stick to A/P
I'm going to do BGP as well, and even that can work fine with A/P instead of having 2 separate BGP peers with A/A and BGP metrics.
i'm just wondering why people would have chose A/A then have issues with apps later on...
