Question about DST-NAT

RouterOS General
1

I have a Mikrotik with a DST-NAT rule where the inbound IP is
72.249.59.40:587 → 72.249.59.40:2525 and its working great. I move the application to another IP and it stopped working


I changed the dst-nat action from IP 72.249.59.40:2525 to 72.249.59.45:2525 and it refused to forward the packets.

My server has the port open and I can access that ip/port locally, but Mikrotik won’t forward the packet from outside my network. I must be missing something as to how the destination nat works. I don’t have a local network. All my servers have a public IP.

Do I use another action item to do this?

Thanks!

Make sure to power cycle the router. I have noticed that DST-NAT has some issues on change which are solved by a system restart (probably related to connection tracking).

I think that’s what it needed. I restarted the Mikrotik and it worked.

Thanks!
