DHCP? problems on USG110
Hi together,
I've been having a problem with DHCP (or I think it's DHCP) for a few weeks now.
After several attempts, I set up the USG after a factory reset.
The problem persists and I cannot isolate it.
I have installed the latest version 4.73 ZLD.
The problem: I have devices here, including two company laptops that I use in the home office, and when I connect them via cable, I "often" get an incorrect IP address assigned. My LAN is 10.0.0.0/23.
The best misbehaving I see this with the HEOS speakers, which I have assigned a fixed IP, but according to the USG log, they get a 192.168.0.x address and are rejected (blocked). (Even if I connect them directly to the USG).
Over WIFI everything works as if the problem does not exist.
The APs are connected to the same switches I am trying to connect these devices to.
If I keep the company laptops connected via cable for a long period of time, they eventually get an IP and I can then work. This has not worked with the HEOS speakers so far.
Do you have any idea, do you need more information?

Hi Zyxel_Cooldia,
Thank you for this trace call - packet-trace interface lan1 extension-filter net 192.168.0.0/24. that solved my problem.
I switched off and unplugged all devices afterwards. After that this trace showed one device. This was a KNX Smarthome visualization. The electrician forgot the service switch during installation. Thus, the device was in configuration mode with a DHCP server. Did not think that this device would also have a DHCP server.
Thanks for your support0

Hi @bavaria,
Does the USG110 have any interface IP is subnet 192.168.0.x/24 and DHCP server is enable on that interface?

Zyxel_Cooldia,No.I have tried many things among others, I have changed LAN2 to different 192.168.x.0/24 subnets, but this has not resulted in any response. Currently LAN2 is disabled.0
