Inbound Firewall Rules on 388 firmware

[Roki100]

Hello! I have upgraded to the 388 firmware and i notice theres a new firewall section for IPv4, however i cant seem to truly understand what it is for and what it does, as there is no explaination on both webui and asus website, does someone maybe know?

Is it any similar to what we get in Network Services Filter?

Careful with this one because there was a firewall bug in 388_21709 and I don't know if it was fixed in 388_22068:

Release - ASUS RT-AX86 Series(RT-AX86U/RT-AX86S) Firmware version 3.0.0.4.388.21709

Since you’re running stock firmware, this would be a prime opportunity to report the issues you’ve noted to ASUS using the Feedback tab. Yes, this is what I did with the previous 388 firmware. I need to play with this one a bit more.

As the header says, this one is specific to inbound connections, while the Network Service Filter is more about outbound connections.
