@TP-Link 

I have the same problem and very much interested in this feature, please add me to the list of requestors.

I have upstream gateways which also require visibility of the original IP address,  but need to keep router mode enabled for QOS of wireless clients.

I also note this is a fairly common question,  a few other threads on this site with similar questions eg,

Thanks.

I support this request as well.

My use case is the following:

Two ISP a Tp-link 470t load balancer in front of 5 deco x60. I want to use the antivirus feature provided by deco but I need to route some of the deco clients to a specific ISP (they are a set of skyq decoders so they need to be seen under a common ISP)

I also require the feature of ad-hoc mesh networking with NAT turned off, in bridging mode. The ISP provides a router with NAT, I don't want a second one as it prevents access between servers and devices in my home network. I don't want to run the Deco routers in the hotspot mode because I don't have a high-speed backbone network available.

 i'm suprised this isnt more of a supported capability.  You can get rid of the NAT by using AP mode but at the expense of a number of features (see below).  For me this is a non issue as I am a Cyber Security person so my hime network is locked down pretty well.  The one thing I do miss out on in AP mode is the capability to vlan on the wifi.  This is something I really need.

Seems a small ask to have an option to disable automatic NAT (maybe hidden away so your average user doesnt turn it on accdientally and kill their internet).

This one lacking feature is probably going to be what makes we replace the entire Deco system which is a pity becuase its been itherwsie flawless and other competitors I have setup like Orbi and COVR have been less that stable.
