By default MikroTik has Firewall enabled that block's all traffic initiated from wan side except dst-natted rules. Please try this port forward rule:
/ip firewall nat
add action=dst-nat chain=dstnat comment=port forward dst-port=8888 in-interface=WAN1 protocol=tcp to-addresses=10.155.15.2 to-ports=8888
WAN1 is my wan interface. Please change it according to your setup
I Will try this in the night, yesterday I move a server in the nigh
I very very tired.
can you ping your wan IP from the Internet?
enable filter rule that accept ICMP on the input chain first.
I don try this, I test this too in the night
The external WAN IP is right, I look it searching in the router config and late in whatismyip.com
of course on the DVR network you have the gateway IP pointing to the Mikrotik, right?
Yep, The DVR that is a PC is pointing to the gateway. (IP, DG and DNS)
I Configure the TP-Link same as the Mikrotik. If I put the tplink all work fine, if I put the Mikrotik the DVR can surf and the cameras only work in local mode, not from outside.
Thank for the help!! I need to configure all this device to start workin in some bussisnes . Than for helping me
