Hello Indan,

thank you for your fast response. I was not aware of that. I would need at
least an option for a hard separation (DMZ) for specific interfaces. What do
you think is the best point to implement that? In ip_input or ip_input_accept?
Do you have implemented it and how did you implement it?
With Kind Regards,
