Hello everyone, today I needed to check a traceroute from an ORG that had difficulties reaching a website. So I went here on "old" firewalls: to check it and there was the option working properly, while on some other sites with newer firewalls like USG FLEX 50H I had no option to have quick network tests like Ping,…
Just updated the first 200 H with V1.39 firmware and DYNU updates are failing with an event error: Update the profile <*****> has failed because Username was empty. DYNU setup screen has no Username field. Is anyone else experiencing the same? Marcin
I keep getting handed USG FLEX H firewalls I didn't set up, and before touching anything I want the basics: which zones and VLANs exist, where traffic is allowed to go, what is reachable from the Internet, and whether the rules contradict each other. The web interface shows policies, objects, NAT, VPN and routing each on…
I manage client networks built on Zyxel equipment from a Linux workstation, and two tools I use every day only exist for Windows: ZON and SecuExtender. So I wrote Linux versions of both. Each one is a single Python file that needs only the standard library, and both are on GitHub under the MIT license. ZON for Linux…
Traffic between LAN1 and LAN2 is extremely slow. I am not sure if replacing the USG with a more modern device would solve the issue. So, I was considering a Layer 3 switch to handle the traffic between the two LANs. Is this a viable solution? And if so, could you recommend a suitable product?
I have a Zyxel RGS200-12HP switch that I would like to factory reset. Unfortunately, I do not have any login password, so I can only access the device through the serial console. Could you please provide the official procedure for: Reflashing or reinstalling the firmware via serial console (e.g., XMODEM, TFTP, or other…

Hello Zyxel Community,I am writing to seek assistance with my Zyxel NR5111 router. I purchased this device from an open-market reseller in Germany, believing it to be a standard non-branded unit. However, after some monts, I realized the router is locked on a specific provider's firmware branch. Here are my current system…
One of our clients is experiencing issues with their internet connection, and we would like to monitor it via Nebula. The firewall (USG FLEX 200) has been added to Nebula in Monitor Mode, but it does not appear in the monitoring view. Only the switch and the access point are visible. Where can we monitor the firewall in…
I have mikrotik router connect directly to switch with vlan trunk and I buy USG Flex 200H to install as transparent bridge between mikrotik and switch to filter URL/app. First, I try to test by bridging p1,p2 (no vlan) and USG can filter traffic normally, But when I try to bridge vlans in p1,p2 , USG can not filter traffic…
So not sure about all models but on my old USG models I import a .pfx that has root, intermediate, certificate and key it imports fine but as soon at you set it for WWW the whole USG locks up plus port 80 needing a full reset the fix is you only need certificate and key in the .pfx
Hey Zyxel community, I have 4 NWA130BE distributed in the building and basically configured exactly the same way (except individual properties) and supposed to work as a "mesh" network.

Hi, I am new to the Zyxel XGS1935-52HP managed switch. I wanted to limit access to one device for one port using MAC address. However, I couldn't find the option to do so. According to google, using port security and set the learning number to 1 and it should work. I tried and the port just assigned another IP address.…
Hello, I lost my admin password for this switch, i am connecting with serial port but i don't know who to reset (retrieve default login) for this switch. Many thanks for your help. Regards
I've spent a lot of time diagnosing this, and whilst any official bug report has to come through my ISP, who are more likely to just try a different brand, I think it worth making this public through the forum. (I see postings for this model, even though the forum might only be officially intended for direct to consumer…
