Hi Nima,

I can confirm this issue. I believe this is a bug in IPFW3.

Hi Bill, would you please have a look? Actually, "ipfw3" cannot add any
rules,
complaining "ipfw3: getsockopt(IP_FW_ADD): Invalid argument". Thanks.

Cheers,
Aaron

Hello,
We are working on a project that includes DragonFlyBSD and IPFW3. On
this phase of project we are trying to test all features. Based on
official DragonFlyBSD
documents(https://www.dragonflybsd.org/docs/ipfw3/) for

using

stateful firewall and checking every traffic state, we must use

"ipfw3

add

check-state" rule. When I use the syntax I got this error :

1. ipfw3 add check-state
   ipfw3: getsockopt(IP_FW_ADD): Invalid argument

Hi Nima,

Did you load the necessary modules? If not, try and load all IPFW3
modules, i.e., "ipfw3", "ipfw3_basic", "ipfw3_layer2", "ipfw3_layer4",
and "ipfw3_nat".

Hope this solves your problem.
