Monitoring Outbound VOIP Traffic on WatchGuard Firebox

Hi everyone,

We recently installed our WatchGuard Firebox, and so far, everything seems to be running smoothly.

As part of our setup, we have a firewall policy and an SD-WAN action in place to ensure that all VOIP traffic from our on-premises telephone system is routed through a specific WAN interface. This setup appears to be working as expected.

However, I’d like to verify that the VOIP traffic is indeed passing through the designated WAN interface. Is there a way to check traffic logs or monitor outbound connections from the phone system to confirm this?

I’m still new to WatchGuard and learning my way around the system, so any guidance would be greatly appreciated!

Thanks in advance for your help.

    Some options for this:
    . enable logging on the policy allowing out VoIP traffic. On outgoing Traffic Monitor log entries, the src_ip_nat will show the public IP addr of the outgoing packet, which should indicate which WAN is being used for the packet

    With WSM Firebox System Monitor:
    .HostWatch will show source IP addrs and the external interface being used for outgoing packets
