How to forward a port from a tag button?

Question

Mikrotik

There is an alarm button with an IP address (internal)
192.168.0.169
It sends packets to the OBO console
88.135.48.138
The ports seem to be forwarded, there is a rule.
The connection is not working, what could be the problem?

Answer 1

Sr_Fill : Is OBO accessible from your external address? The fact that it responds is not yet an indicator.
For example, you need to connect to the OBO on port 1234. Try to connect from your office with a telnet, something like this
telnet 88.135.48.138 1234
where 88.135.48.138 is the address of the OBO server (if I understand correctly).
Monitor what traffic goes from your button to this address - Torch function on Mikrotik (on the interface)
Look at the internal interface, look at the external one - if the connections go to the OBO server, then there is already a problem with the OBO server - kick it to the admin.
If the problem is that it does not pass through the Mikrotik (a connection is observed on the internal interface, but not on the external one), then there is already thinking why this is so. For now, I won't say more.

Ummm, what are you even doing? Why do you need to forward ports to the outside? There is a masquerading mechanism for this (or regular general NAT). Do you need to go outside from a different (not a common address)? Or do you have multiple routes/interfaces?
