L3 Networker

Hello all.

I have a networks design question with PA-500.

Customer has 4 ADSL internet lines from 2 different ISP. (ISP-A offer 2 ADSL lines, ISP-B also offer 2 ADSL lines.)

Customer want to configure Active Active with 4 ADSL lines.

I found article from knowledgepoint. (

But it is just explained active-standby with multi IPS.    

Is it possible to configure an active active with 4ADSL lines?

Please refer attached simple diagram.

Theoretically it can be done, but it would a complex network configuration. To get exact details you need to contact the SE's in your area.

If I were you, I will not delegate this kind of features to the firewall. I don't even known if it's possible...

You should go to a ISP load balancer device like Peplink.

I'm have already install more than 20 and ALL customers are really happy with this one.

PS: I don't work for Peplink company...
