Need suggestion for 2 x internet data line network design

[jeremylo]

The office has 2 internet data line. Each of them has a fix public IP address. Device is a PA-820.

I want to separate the utilization of the data line as below.

1. Office area/staff primary use 1st data line. If this line down then auto change to use 2nd data line. When 1st data line resume. Auto change back.

2. Guest area always use 2nd data line.

What configuration can achieve this goal?

Assuming the Office area/Staff and the Guest are on differnet zones you should be able to use PBF rules.

PBF is not dependant on the ZONEs could be IP/SUBNET/USER....

Hello,

I successful achieve this by using PBF and set different Metric number for the 2 interfaces in default route.

But found a problem. The 2nd interface (with higher metric number) cannot ping or being ping from outside. I think asymmetric ping was happen and look like it was caused by PBF.

Have you enabled PING in the interface management profile?
