Nat instead gateway

[ghassen6121996]

Good morning guys.

Is some project we were obligated to configure the router without touching any end device..

In Normal case this end-devices should have their own default-gatewy ..

So how we will connect these devices there's another way access them and to ping them ?

Can we use the nat instead the default-gatewy ?

Hello,

what is the context of your question ? I am experiencing a classic case of 'I have absolutely no idea what you are talking about'...

Please provide some more additional information. What topology is that, what do you want to achieve ?

hello i find a solution by myself ..

mabye I didn't explain enough the problem .

the situation was that i was obligated to integrate a network through a system without touching the end-diveces in order to communicate with them so i can't giving them the default gateway of my router .. so i cannot ping them. 

the solution that i find is to use access list permit any any .So with that  i can access the end devices without  give them a default gateway from my side .

As I understand you have Router and need to shift all Device use this router as GW to other GW ??

start from the DHCP change the default GW and wait until all Device use new GW then you can easily reconfig the old router.
