Hi,
First of all, I'm newbie to Mikrotik RouterOS but I try hard to study about this great OS.

My problem:

Introduction:
I have a Mikrotik CCR1036-12G-4S. I have a network with more that 200 ubnt antennas (sectors, rocketdishes, hotspots etc).
I use 172.19.0.1/22 for my antennas. My server has 172.19.0.1 and my pc which I used to manage my network has 172.19.0.5, as an ip (which is bind).
I use 192.168.96.1/19 as ip pool for hotspot and pppoe users.

The issue:
From my pc, when I try to connect to the interface of one of my antennas which is on 172.19.0.1/22, everything is ok.
From my pc, when I try to connect to the interface of one of my antennas which is on 192.168.96.1/19 (it uses pppoe, for example), then I cannot reach it.
I setup NAT with these settings, using winbox:
(IP > Firewall > NAT > Add)

Tab General:
Chain: srcnat
Src. Address: 172.19.0.0/22
Dst. Address: 192.168.96.0/19
Out. Interface: br_hs (which is my hotspot interface)

Tab Action:
masquerade

but I wasn't able to reach my antennas which is on 192.168.96.1/19. Any solutions???

Thanks in advanced.

Out. Interface: br_hs (which is my hotspot interface)

This must go to the interface connected to your ISP

Finally the solution was in mangle. I've just added this line, and everything is ok now.
Thanks in advanced.
