How to Make DNS NAT - im trying and all fail :(

Hi Folks

Im trying to do a DNS NAT. In short, Ive got cheap IPCam which doesnt allow to comunicate directly with its own mobile app, it does it via some server.

So ive checked, where Mobile app is making a requests. Ive found that its: 123.56.159.92. Cam is on separeted Vlan droped to go outsite. Lan Ip is 10.0.100.100

So my goal is to make scenerio when if app is trying to request public server then NAT should translate it to local Ip(cam).

Im using my own DNS server at home (adGuard) FW policy is set.

This is only my experiment.

I dont know if im understand the gui implementatin but ive tryied sth like this

Can you please advice sth ? how to achive it in NAT GUI ?

So this is how it works

RED color is how it works right now
BLUE is how i want to be.

I hope this diagram will help, im not good at it :D

If you would draw a picture for us, maybe we can help you.

Do something like: Client - XG - Server (Internet)

What should happen with the traffic? Because i cannot follow your request.

I am not sure, if this will really work. Did it work with your old solution and NAT? Because this looks like breaking the routing completely.

its just an attempt to see if its going to work. Why im even asking about NAT for particular scenario ? Well i was trying to setup a DNS NAT but no luck at all so maybe i didint understand sth as Sophos implemented on GUI ;)

Hi LuCar Toni,

what he is trying to do is have all DNS requests that appear on the XG internal interfaces are redirected to his own internal DNS.

Sure thats tru, but for that scenario ive created a separated topic ;)

In this case im trying to achive if ipcamAPP which is requesting to public ip -> this request NAT to local IP of an IPCam

So i wrote on diagram

IPCAM ->NAT -> LOCALIP CAM. To see if i can bypass public ip server of IPcam vendor. I hope this is explained correctly ^^

Im refering to this yt video:

so if this would work with DNS why it shouldnt with some other services ;)
