@JonathanLee If using suricata, it is recommended that you disable LRO and hardware checksum offloading.

@mcury Thanks for the reply,
I do not use Suircata only Snort and Squid. I just always wondered what is recommended here for years.

I don't think that there is a difference between Snort and Suricata when it comes to LRO/hardware checksum offload..

@mcury My issues is the 2100 is an ARM so it can't run inline mode and will not load *.SO rules.
So is this a different on the 2100 @stephenw10 @bmeeks
I have always wondered about this for years

Checksum offloading is enabled by default and should work on mvneta.

According to bmeeks, not when you are running Snort and/or Suricata. Legacy mode or not.

@mcury Thank you
-
Yeah I would disable it with Snort. Though I'm not aware of issues with it in mvneta specifically. It really doesn't help much so disabling it won't hurt.
-
@stephenw10 Than you for the reply
-
The IDS/IPS packages prefer checkum offloading be disabled. And in many (or even most) cases you could expand that to "require" it be disabled. You are usually better off disabling all the hardware-assisted features such as LRO, checksum offloading, etc., when using either of the IDS/IPS packages.
