How to add a forwartingrule:

Firewall settings

Firewall -> Settings -> Advanced:

- Reflection for port forwards: Enabled
- Reflection for 1:1: Disabled
- Automatic outbound NAT for Reflection: Enabled

then save and go to Firewall -> NAT -> Port Forward -> Add

I use the example from the source here. recap:
– You have a host with IP 192.168.1.200, with port 3100 open TCP.
– You want to port forward from the outside 9999 to 3100.

- Interface: WAN
- TCP/IP Version: IPv4
- Protocol: TCP

Under Source > Advanced:

- Source / Invert: Unchecked
- Source: Any
- Source Port Range: any to any

- Destination / Invert: Unchecked
- Destination: WAN address
- Destination Port range: (other) 9999 to (other) 9999

- Redirect target IP: 192.168.1.200
- Redirect target Port: (other) 3100

- Pool Options: Default
- NAT reflection: Enable
- Filter rule association: Rule NAT

Now it should work! But if it doesn’t (in my case) try the following:

from external: telnet <your external IP> 9999
from internal: telnet <your external IP> 9999

Does the call from external not work, but from internal it does? Then look in the livelog if the query even get to your firewall: Firewall -> Log Files -> Live View

If the query doesn’t show up maybe the error is before the firewall. In my case it was a NAT in the Fritzbox (even I have a external IP). I had to set the “exposed host” rule in the router. This is nessesary by newer Fritzbox models (in my case 6591 Cable).

The ASUS PCE-AC88 is a strong and powerfull card with a little flaw:

The driverpackage that Asus provides is Version 2.8.0.7  from 2018/04/13 [link]

The driver in this package is version 1.558.48.8 from 2016/09/06

The device-name im device-manager with this driver is “ASUS PCIE-AC88 802-11ac Network Adapter”

My Windows 10 (newest patch 2020/04/20) crashes randomly with this driver whenever the system is under heavy load (any heavy load, not only networking).

After some searching I found the Chip which this card uses. It is the Broadcom BCM4356 and I found a newer driver for this chip.

Because I hate installationpackages I repacked the driver so you can install it without bloadware

Broadcom BCM4356 Wireless LAN Driver (works for ASUS PCE-AC88): [link]

This driver had version 1.558.53.1 from 2017/10/22

After installation the device is not longer an “ASUS”. Now the device-manager sees it as “Broadcom 802.11ac Wireless PCIE Full Dongle Adapter”.

With this driver for me all crashes are gone!
