Internet access from Asus ZenWiFi Access Point

Networking
1

I just replaced an old Netgear mesh WiFi system with an new WiFi7 Asus ZenWiFi BT6 three node system. After the initial network setup (IP - BLUE.2, gateway - BLUE, DNS - BLUE, SSID) is complete the AP is accessible both from Green and Blue.

The first issue is that no device on Blue can access the internet. This includes the AP itself. Because of this it cannot reach an NTP server. I believed this to be the issue. The WebGUI allows the ntp server to be input. However, putting the Gateway IPV4 address does not set the time. I ssh’ed into the AP and set the system time using the data command. The logs show the correct time but there is still internet connection. Additionally the WebGUI is reporting that “The system time has not been synchronized with an NTP server.”

I created a firewall rule that allows the AP full access to the firewall device. This did not solve the problem. There are no entries in the Firewall Log pertaining to the AP.

I cannot ping devices on Blue from Green. Before the new AP I could ping hosts on Green, but now I can’t reach them.

I’m hoping someone else has gotten an Asus system operating. Thank you in advance for any suggestions.

The Asus System is router based. IDK if former Netgear was AP based or not.

I think a bit more detail should be given to understand better your current configuration.

Both systems can operate as a router or an access point.

What additional detail can I supply to help?

Still not working but a bit of an update.

I have removed all MAC filtering on BLUE.
I have a Firewall Rule the allows the Access Point full access to GREEN.

Hosts on GREEN can ping hosts on BLUE.
Hosts on BLUE cannot ping hosts on GREEN. This is odd considering there is a Firewall Rule that gives Laptops full “All” access to the servers on GREEN However, they can ping the AP, the BLUE IP, and the GREEN IP.

One additional item. Below is a dump of the iptables on the AP.

iptables -S

-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT

Next update.

As an experiment I hard reset the AP and then reconfigured the system. No change.

Then I installed and old Buffalo DD-WRT AP. The exact same issues.

Therefore, it must be IPFire blocking access. I however cannot find any clue as to where to look for the solution.

I am closing this since the issue has nothing to do with the Access Point particularly.

FYI

I found the cause.

I have not used the Web Proxy in years. It has been disabled. The issue was caused by the Firewall Option “Drop all packets not addressed to proxy” being ‘on’.

As soon as I changed it to ‘off’ everything worked as expected.

Thanks for sharing your experience.
As a matter of facts… Asus ZenWiFi was not the actual issue :slight_smile:
