NAT port forwarding problem

Hello,

I am trying to setup port forwarding from port 3390 on my router to port 3389 on a computer on my local network.

Here is my “/ip address print detail”:

Flags: X - disabled, I - invalid, D - dynamic
 0   ;;; default configuration
     address=192.168.88.1/24 network=192.168.88.0 interface=wlan1 
     actual-interface=bridge-local 

 1   address=10.0.0.200/24 network=10.0.0.0 interface=ether1-gateway 
     actual-interface=ether1-gateway

Here is my “/ip route print detail”:

Flags: X - disabled, A - active, D - dynamic, 
C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, 
B - blackhole, U - unreachable, P - prohibit 
 0 A S  dst-address=0.0.0.0/0 gateway=10.0.0.138 
        gateway-status=10.0.0.138 reachable via  ether1-gateway 
        scope=30 target-scope=10 

 1 ADC  dst-address=10.0.0.0/24 pref-src=10.0.0.200 gateway=ethe
        gateway-status=ether1-gateway reachable distance=0 scope

 2 ADC  dst-address=192.168.88.0/24 pref-src=192.168.88.1 gatewa
        gateway-status=bridge-local reachable distance=0 scope=1

Here is my “/interface print detail”:

Here is my “/ip firewall export”:

    192.168.88.200 to-ports=3389

As you can see, I have two port forwarding rules. While forwarding 3389 → 3389 works, the second rule 3390 → 3389 does not.

Could anyone please explain to me, what am I doing wrong?

Thanks

Someone please close this topic. The problem was in another part of the network. Everything is working fine now :blush:
