Opnsense with Zenarmor Free, block but not

[Philippe]

Hello,
I am currently testing Zenarmor Free on OPNsense.
The product looks interesting, but I am encountering a strange issue.
The connection logs indicate that a connection has been blocked (there is a red shield icon), but my internet service provider, who uses Abuse, reports receiving an alert.
I might have misconfigured something in OPNsense or Zenarmor, but I'm not sure what it could be.

Does anyone have any ideas?

Please see the attached screenshot.

Thx

And I would like to specify that I have configured it in Bridge mode (L2).
LAN, WAN, Bridge, and MGMT interfaces.

Hi,

Did you create bridge on OPNsense or Zenarmor? If it is created on OPNsense, which interface do you protect on Zenarmor?

[Philippe]

Good question.

I created the bridge mode in Opnsense (as indicated in the doc) then I installed Zenarmor.

I have:
LAN: bce1
WAN: bce0
MGMT: em0
Bridge: bridge0

On Zenarmor, I checked bce0 (lan) and bce1 (wan). I don't see any other interface under Zenarmor.

Sorry, I'm new to this product  :)

Hi,

No worries. I'm not sure about your ISP detection but, Please protect only inner LAN side interface of the Bridge on Zenarmor.

Hi,

I believe the ISP detection is correct.
Additionally, it blocks internet connection if there are too many issues, so I need to find a firewall that blocks effectively.

If I protect the LAN interface, will it also protect against external (internet) attacks ?
But problem if I protect only LAN: "For Bridge Mode, you need to assign an interface for each of the lan and wan security zones."


So if I understand correctly ;) I should let Zenarmor handle the Bridge and not configure the Bridge in Opnsense?
