I have been using the “Drop-In Gateway Mode” for few days and it really rocks although I have had no previous experience with it and not sure that I am doing it properly. Basically I am unable to work without my main router (Draytek) as I require WAN Link that GL.iNet does not support. The Draytek, however, lacks a lot of the features that the Slate AX supports and so I am forced into a terrible double NAT situation causing me all sorts of problems with remote access, VPN and routing policies. Now enter the black magic of drop-in gateway: My Draytek will handle all the NAT but my Slate AX can see all the IP client as if they belong to it. The Slate can work on all my network devices as if they are connected to it (when in fact none of them are in my case). I am therefore able to now use things like the DNS and VPN capabilities of my Slate AX on my network as well as the features on main Draytek router without having 2 separate networks. It has basically allowed me to amalgamate the features of the two different routers into one. The only problem I have found so far was that this feature does not respect the VPN policies although I have found a workaround for now.
