Hi there. I've tried to figure my way out of this issue, but no luck.

Desired result - Internet -> Hotel Router (192.168.110.0/24) -> My HAP-Ac2 (172.16.1.0/24) -> my devices (wired) 172.16.1.10-20

WLAN1 = connected to Hotel Wifi in station mode. ***CAN ping internet***
ETH1 = PoE In via injector, LAN side goes to a dumb 8 port switch.
Bridge (172.16.1.1). ***CAN ping internet***

PC - Gets IP (172.16.1.x ; DNS 1.1.1.2 ; 1.0.0.2) but can NOT get internet.

Thank you for your assistance!

Thank you for your assistance Ca6ko.

I've removed all entries under Bridge - ports & ran the commands you provided in the terminal. These are accepted as you can see in the export below.

The bridge can no longer ping 1.1.1.1. As soon as I add the bridge, then the bridge can ping 1.1.1.1.

Do you get an IP address in the DHCP client?

EDIT: I rebooted my HAP Ac2 and I do have internet on the LAN now Thank you @Ca6ko. DESPITE the bridge not being able to ping 1.1.1.1. Is this expected?

HI erlinden

Yes I do (WLAN1 192.168.110.48/24) which is part of the hotels IP range. It displays the following:
IP/ DHCP Server / Networks
Gateway 192.168.110.1
DHCP server 192.168.110.1
Primary DNS 192.168.110.1
Secondary DNS - N/A

On my windows device I get:


Ethernet adapter Ethernet:

Connection-specific DNS Suffix . :
IPv4 Address. . . . . . . . . . . : 172.16.1.254
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 172.16.1.1

I think if you want to test ping on your router, you should select the WAN interface. Bridge isn't able to ping 1.1.1.1 on my RB box as well.
