Hi @GLou
As your scenario, USG is behind a cisco device and it offer 192.168.2.x IP to USG.
Since USG default LAN2 IP address is 192.168.2.1/24. WAN and LAN IP has overlapped.
You can change default LAN2 IP address to other IP subnet then will able to access to internet without problem. (e.g. 192.168.20.1/24)

Guys thank you but nothing seems to work. I have connected pc with zylex in lan4 and internet router in wan1.
I have also changed ip to avoid conflict.
My pc gets connected with internet but zyxel does not connect in internet and setup does not continue.
Is there any other way to avoid setup and get directly into zyxel administration?

Either its a faulty unit or your ISP is blocking the setup test? or a routeing iusse for the test.
What does the test need to complete?
Can you try with the Cisco modem in bridging mode or modem mode.

Hi @GLou
The initial setup wizard will send ICMP to 8.8.8.8 to check internet connection status.
If there is no any reply, then status will show fail.
Can you make sure if Cisco gateway is able access to internet and allow ICMP packet to Internet?

I have taken ZYLEX to office where I was able to continue setup. I have brought it back home however when I try testing 'test internet, it fails again.
My PC is connected to LAN1 port 2 and internet is fine.
But when i try running wizard seup or test internet in dashboard, it fails!!!
I ping internet router and replies 4ms?
What is going on?

Hi Glou,
i've a short view in your post and reported problems with a USG.
The USG60W is connected to your ISP Router (WAN1 to ISP Router) ?
correct ?
Have you disabled the NAT on the WAN Interface of the USG to avoid double s-NAT ?
if not sure, check the option on the USG
go to Configure icon, Network, Interface (TRUNK at the top)
- show advanced settings
- disable the option "Enable Default SNAT"
- save
Configure a static IP of your Network-Segment, that is used between WAN1 (USG) and your ISP Router. Gateway from the USG view is the internal IP from your ISP router.
The next step is to configure routing information on the ISP Router. The ISP Router require the information of all your Networks, that are configures and used on your USG Firewall to send the reply packages for this networks back to the WAN1 interface at the USG.
In my mind, the wizzard can be used for simple configuration, if the USG is directly used as ISP Firewall.
Have fun and good luck

Thanks Christian for your time. Please note that i have disable NAT and have a static IP. Curtently i have only two cables connected. One in wan drom internet router and one in lan4 which goes ro my laptop.
I attach latest internet router setup and zylex setup.
My laptop has internet through zylex but the zylex wyzard gets my an error when i press 'connect test'
Does it have to do with the ips used? Please advice as it seems everything will go to waste...
I attach pictures for ease
