port forwarding... help!

hello guys
as you can see in this diagram i have two mikrotik routers R2 witch is connected to the
internet through a dsl modem and it’s also provide internet to R1 using pppoe connection
and R1 is provide internet to other clients using hotspot… all i want to do is make the dvr accessible from internet

I’m not sure about the hotspot part, because I don’t have much experience with that.

If there’s route to 10.0.0.2 (so probably to 10.0.0.0/24) on Mikrotik2, then just add dstnat rule with 10.0.0.2 as destination.

If not and you don’t want to add it, then first add dstnat rule on Mikrotik2 with destination being IP address on Mikrotik1’s end of PPPoE conection. And then another dstnat rule on Mikrotik1 to 10.0.0.2.
