Hi, Over the past three weeks, we’ve had three different sites experience downtime because the USG Flex H firewall randomly blocks all outbound traffic. So far, this issue has only occurred on the USG Flex 50H and 100H models. The only workaround I’ve found is to connect to the firewall through Nebula and perform a reboot.…

Hi! I've tried to upgrade the Php-MySql package on my NSA320S using Mijzelf's MetaRepo (thanks again, it works) because the WebUi was always naggig me.

Can Zyxel confirm that each end of the VPN needs to be a completely different block of subnet or can it be different subnets within the same block. So, can the subnet at one end be 192.168.0.xxx and the other end be 192.168.1.xxx? Or do they need to be 192.168.xxx.xxx at one end and 172.16.xxx.xxx at the other? thanks….…
If the answer is No then why four and not only two or one?
In FLEX (non H) series I was able to add a Domain Zone Forwarder in DNS to an IP-Address behind a tunnel. So the other site could resolve server.domain.local for example. I could select Private DNS Server then and then it mentioned "query via tunnel". In FLEX H Series I don't have that option anymore, can only select one…
In the new H series firewalls, firewall version 1.37, the windows script does not include the split tunnel option any more, it has to be done manually via powershell. is this a bug or was it intentionally left out. Or at least it doesn't work. Using windows own vpn client
My firmware update has been going for nearly 30 mins now, the web GUI still has the spinning icon but it just won't end. All I could find was a 5 year old thread about a manual reboot but I don't want to risk bricking the device. I don't have ages and I really do need it online asap.

About a month ago I purchased a pair of XGS1250-12 Ethernet switches and, while there appears to be a fan port on the backs of the switches, I don't actually hear or feel them running.
