ZyWALL USG 200 Random crashes

zywallzyxel

we have an ZyWALL 200 at our work, and for a long time (I'm new here) it's been crashing and restarted once in a while at random moments, mostly during officehours (but not only officehours).

The only theory we have about these crashes is that the log gets filled, the device crash due too no diskspace left, removes the logs and reboots.

The reboot takes approx 5 minutes so it's very annoying for everyone working here.

The SSH Shell on the box is completely useless and the Web Interface does not say that much…

Does anyone have experiences like this and solved it? Or am I on my own, just started to try to trace it down, so I keep stats of flash usage on the device and I will try to predict a crash by letting the flash get filled.

One other thought I have is to get rid of it and place a computer there instead.

I'm having the same problem. What is the Firmware you are using? My USG as a Fiber (4Mb/4Mb) connected to Port1 in a valn from operator. I'm using the latest firmware avaiable. Anti-virus, ADP, IDP, Content Filter and Anti-Spam are turned off. The Zywall is connected to a 5KVa UPS, with other equipments that don't have the same simptoms. I've replaced the first USG 200 to another, imported the config and the problem is the same.

VPN using Zywall

I have used ZyWALL a few years ago. It was very simple... The only things required were activating the VPN module, specifying local and remote address ranges, and specifying a key. I used SSH Sentinel to connect to the remote private network.

If you use SSH Sentinel, you may have to click on Acquire virtual IP (or something like that) to be assigned an IP from the range of the remote private network (due to the settings of said private network).

It might be a useless question but can those two machines connect to each other?

Edit - make absolutely sure your subnet mapping is correct - example:

ZyWALL A - Local:
  Address Type  = subnet
  IP Addr Start = 192.168.10.0

ZyWALL A - Remote:
  Address Type = subnet
  IP Start     = 192.168.20.0

ZyWALL B - Local:
  Address Type = subnet
  IP Start     = 192.168.20.0

ZyWALL B - Remote:
  Address Type = subnet
  IP Start     = 192.168.10.0

This will map the subnets so the computers can see each other. Of course, you NEED to configure your local computers properly - the network configuration of the remote computer should be done in a way, that if you brought said computer over to the local network, it would be accessible.

So configure your network masks, firewalls and routers on servers and client computers so they can communicate.

ZyWALL configuration is so extremely simple that even a basic user should be able to configure it properly. The rest of the network is usually the problem, not the ZyWALL config.

Router – ZyWALL USG 200 – dynamic DNS for clients

I got an answer on Zyxel forum directly:

Unfortunately, this feature is not possible with current firmware :(
