USG behind firewall - use in transparent mode

Hi,

I have been reading for hours on if / how to use the USG in transparent mode, i.e. no NAT and only used for logging and info. 

What I have read spans several years and firmware versions so I just wonder what is the *current* cookbook to setup the USG in a scenario like this?

 

I want to monitor TWO different subnets a behind the firewall, so basically I want WAN1 > transparent to > LAN1 and WAN2 > transparent to > LAN2 while WAN1/LAN1 and WAN2/LAN2 should be isolated from each other.

Thanks a lot for comments and advice on this.

 

regards Tor

I am afraid it is not possible yet.

We are on the brink of replacing our Cisco L3 router/switch and I would really like this as well.  It has been in the "pipeline" for a while now, but never seems to make it to production.  

 

If you search around, you can find some hacks that kinda accomplish it in a vague way.  I tried them all and they don't work quite right.  I pre-ordered the xg-gateway (hoping this was something already available), and was trying to accomplish the workaround on our sandbox sg-pro model.  

 

No luck so far.  Plus this really needs to be a supported software feature.  Because if is always going to be some CLI hack, it will likely be wiped every firmware upgrade.
