USG200 ethernet and vlan in same subnet
Accepted Solution

Looking at this but not fully tested at my end this may not be possible and the USG 200 ( unless FLEX) is old and no longer updated.
The way this might of worked is if the port role option allowed a OPT with another port this way you have only one 192.168.10.xxx subnet. With the way you have done two of the same subnets makes them isolated.
The way round this is to get a VLAN switch connect the OPT port to it and switch to Cisco C3560-G with the VLAN's and the laptop to an untagged port to VLAN 10 on the switch so that the laptop sees all of subnet 192.168.10.xxx.

You should be able to create a bridge interface on USG200 to bridge lan2 and vlan10 interfaces.You would remove the IP(0.0.0.0)/subnet(0.0.0.0)/dhcp/etc 'layer 3' settings from lan2 and bridge interfaces. Then you should be able to access vlan10 devices/subnet via any ports assigned to lan2 interface.0

^...As long as the laptop is VLAN tag to 10 yes

@PeterUKThank you for coming back to me, I also raised a case with Zyxel support, they have also just replied.It seems that you are correct, it isn't possible to do what I want with the USG.Unfortunately, putting another switch in the cabinet next to the USG is not really possible, there is no 240v power, nor any physical space really.I guess my only real option is to ditch the Zyxel, and replace it with the ASA5505, which I have several 'spares', and already have the identical setup in several other locations which works perfectly.I was just trying to make life easier by re-using the existing Zyxel USG200 (customer provided).Thanks again,Kind RegardsTony0
