So I have configured my XG in what I think is the correct manner, but am having a persistent issue because of it.
Overview:
The phone system vendor that we work with was having bandwidth issues. We share a modem that is handling addresses from a static block. The XG is sitting on one address and the Phone on another. During high traffic periods the XG would eat the entire pipe and crush the VoIP to the point where it would no longer be able to maintain communications. They (phone vendor) wanted us to put the phones behind the XG.
Deployment:
The internal network interface (x1) in the LAN zone. x.x.123.1/24
The external network interface (x2) in in the WAN zone. x.x.x.68/29
I created a new internal network interface (x3) in a new VoIP zone. x.x.10.1/24
I created a new external network interface (x4) in the WAN zone. x.x.x.69/29
I then created traffic shaping policies such that x3-x4 has a minimum pipe.
I finished with my firewall rules so that traffic is passing out of VoIP to the WAN (x4) and all the needed inbounds are passing through.
Issues:
The Interfaces keep showing the x4 as offline/online/offline/online. And every time is does it emails. But it's still passing traffic. I extended the timeout of the fail-over to the maximum to keep the noise down, but that's not a solution.
Questions:
Is the above configuration the optimal configuration?
How do I keep the WAN interface from flipping out?
Should I be doing this different?
