Strange problem with 6.11

RouterOS General
1

Hello everybody! I met a very strange problem. I opened a port to my laptop. This port is 40000

If i enable this port forwarding, i can not login via IP only with MAC, and the Internet connection disconnect as well.

Chain=dstnat
Protocol=TCP
Action=dst-nat
To ports=40000
To addresses=192.168.100.4 ( Laptop’s wifi IP )
Out-Interface=eth1 ( WAN )

Maybe my config is not correct, but this is worked very well so far, if i have tried to login via IP address, i got the following error message:

Could not get index, fatal error

I understand: From Internet x.x.x.x:40000 TCP to Laptop 192.168.100.4:40000

Chain=dstnat
Protocol=TCP
Action=dst-nat
To ports=40000
To addresses=192.168.100.4 ( Laptop’s wifi IP )
Out-Interface=eth1 ( WAN ) must not be set

missing dst-nat=<ip-of-ether1-without-/xx>
missing dst-port=400000

What you have write, redirect ALL TCP TRAFFIC, FROM OR TO INTERNET TO YOUR LAPTOP, PORT 40000

I found an another thread, in the IP services i allowed the 0.0.0.0/0 to winbox, at the moment working.
Anyway the eth1 at the moment is my " WAN " port: 192.168.1.195/24, this RB 751 connecting to an RB 2011

Hello, I’m new at this forum. And I hope I can help you.

with the 0.0.0.0/0 added to IP — Services — Winbox… It works. but is not good to leave it like that, bec ause of security reasons.

Now what’s th original problem, according to my research. The `problem is that in this rule of firewall we need to put all the internal network’s to access winbox.

From external Address, it’s difficult to know what IP or network we are using every time we connect, but according to my experience, this solution work perfectly for now.
