I have issues reaching exactly one server from exactly one client PC.
The client is connected to our XMG1915-10EP, the server on LAN1 or LAN3 (tested) of the USG LITE 60AX. I cannot ping or RDP or use any other TCP/IP connection to the server from the client PC (but vice versa!). But if I connect the server to the switch it is working. I never had such problems, and they started directly after the firmware update. Even changing the IP reservation of the client, reboote or full power cycles of all devices did not help.
RDP to the server from WLAN or other LAN devices is working!
Will create support ticket directly via NCC and stop all firmware update for our customers till this issue is analysed and fixed.0 -
I also have this problem. After upgrading USG LITE 60AX to version V2.30(ACIP.0) communication between LAN ports does not work.

Issues gone after downgrading to 2.20(ACIP.0) with Zyxel support. Will wait for and test with the next version.

@Zyxel_Jerry We're having the same issue — please help! It seems that L2 client isolation has been enabled for some reason!

This can only be done by Zyxel for this model. Open a support ticket using the "(?)" in NCC and scroll down. But I heard there may be a new version this week hopefully. So, if you can wait a few more days I recommend it.

Hi @Mk88_it @Lohkamp @MrAllegheny @Tricatel
The new firmware has been released which fixed the issue.
You can click upgrade directly on the firmware management page to upgrade to the latest firmware.

Just installed, first impression: described bug above in V2.30(ACIP.0) gone with V2.30(ACIP.1). Thank you.

I installed V2.30(ACIP.1) too and I have NO issues like that via LAN ports, so I think the bug is solved.
