Active | Active Dual WAN

tom.neteng — Fri, 01 Dec 2017 20:54:13 GMT

Can someone tell me what the supported configurations are for an active | active dual wan configuration in regard to physical wiring.

Can I have one ISP connected to one Palo and the other ISP on another Palo or do I need both connected to both, run through a switch with two external VLANs and a virtual IP on either ISP?

I have run Active/Active with the ISP upstream links run directly to the two PA devices. This is an option.

Obviously if there is a PA hardware failure that particular ISP is then no longer available. But in some DC scenarios it makes more sense to lose this ISP then add the complications of the additional devices in line with the service.
