Hi guys, quick question:

I’m running a Zyxel XGS1930 managed via Nebula and configured Port Mirroring for Wireshark like this: Source Port 14 (uplink) → Destination Port 31 (monitor).

In Nebula I don’t see any option to select mirroring direction.
Does Nebula mirror both directions (ingress + egress), or only ingress?

If it’s ingress-only, is there any Nebula workaround to capture both directions?

    Hi @CHGR,

    Regarding your question, we confirm that port mirroring on Zyxel Nebula-managed switches, by default mirrors both ingress and egress traffic.

    The default is likely both but you should see if it is in Wireshark
