ZyWall 110 Stopped Working and Can't Log In after firmware upgrade
My Zywall 110 has been fine for a couple of years. Yesterday, for the first time ever, it required me to change the password and then installed a software update. At that point it stopped working as a firewall and I was unable to log in with either the new or the old password. Effectively, it is bricked. Either someone comes up with a fix or I am going to have to send it back to the factory for repair??

Hi @jschatzman,
Connect console and see if you can enter debug mode.
If you can enter debug mode, follow the FAQ to backup running configuration and upgrade ZyWALL 110 to the latest official firmware 4.35(AAAA.2).
Here is the FAQ for your reference.
How to backup running configuration if forgot password?
If there is no reaction on console or you cannot access the debug mode, you have to send the device to repair center.

O.k. that worked, after I figured out how to get my serial/usb converter to come online in less than 3 seconds.
Now I would like to reattach the firewall to my network for diagnostic purposes. How can I change its gateway address to something other than 192.168.1.1 so it won't conflict with my replacement firewall (e.g., change it to 192.168.0.1)?

Hi @jschatzman,
You can access the device via SSH or console and enter the following commands to change the interface IP.
Router# configure terminal
Router(config)# interface lan1
Router(config-if-lan1)# ip address 192.168.0.1 255.255.255.0
Router(config-if-lan1)# exit
Router(config)# ip dhcp pool LAN1_POOL
Router(config-ip-dhcp-pool)# network 192.168.0.0 255.255.255.0
Router(config-ip-dhcp-pool)# starting-address 192.168.0.33 pool-size 200
Router(config-ip-dhcp-pool)# default-router 192.168.0.1
Router(config-ip-dhcp-pool)# exit
