dynamic dst-nat appears by itself in NAT tab

Hi All,

I have about 20 RB 450G that i manage, but one of the RB has something strange under NAT:

If i go to Firewall > NAT, it has a few dozen DST-NAT (D-Dynamic) set-up which points to few of the LAN pcs/laptops, on various ports. So… this tells me that for whatever reason, there is a Dynamic DST-NAT (port Forward) set-up for few of the LAN computers.

I haven’t seen this before on any other MikroTik’s that i manage.

Why these Dynamic DST-NAT are appearing? What’s causing this and how do i disable it?

Hope this makes sense…

Thanks in advance!

Disable UPNP under /ip/upnp…

Thank you very much! :laughing:
