Intrusion Detection issue - IPS activated - no acces from LAN to network

[morcom]

Hi again...

So I have one issue with Intrusion Detection on my home used firewall.

I'm using this board together with OPNsense: http://www.hcipctech.com/Home/ProductCon?productid=317&english=2

It is nothing powerful - but actually it is fine for small home firewall - and as I have some systems which should be protected - I need as well ID service. Before I have tested ClearOS (works fine - was blocking most unwanted attacks on VoIP server), then SOPHOS UTM 9 (was working fine but it was looking that it was blocking much less than ClearOS - so on my FusionPBX I saw plenty of attacks).

As I was not really happy with the way Sophos UTM was working - I have decided to move to open source... and now - ID is setup - but in any situation I'm activating IPS - whole traffic is blocked totally.
I have IPS active on another OPNsense in datacenter (installed on top of PROXMOX VM) - and I have no issues with traffic from LAN.
At home - IPS activated - no traffic from LAN. No IPS - all works.

Settings on both instances are more less the same....

Any ideas why? Is it related to hardware?

Thanks for any tips where to look.

Hi Mike,

Hardware looks good, no Realtek NICs, very good indeed.

You should disable all hardware acceleration features under Interfaces: Settings and try again after a reboot to be safe. Also make sure that you are on the latest version 16.1.20.


Cheers,
