Ip filter default behaviour!

RouterOS General
1

Hi all,

Yesterday night i have tried to add very basic filter to Mikrotik 2.9.5

My filter command only like that:
/ip firewall filter add chain=input protocol=tcp dst-port=23 action=drop

Then my connection is dropped.. However i connected with ssh..
And tried to connect with another protocol(like web etc.)

I have no success. Then i investigate the problem.. Log in from console
screen. Looking filter rules but i have only one of them!

But its interesting that machine input filter behaviour is drop all packet!

When i remove dst-port 23 rule everything going OK..

So could somebody explain why this heappened?

Thank you..

Works for me. Try to reset your configuration and restore it manually.

Hi all,

Well MT software new installed.. I have only setup my interface..
Then tried to add only basic filter!

I think reseting configuration isn’t good solution for much of case..
Because this is not Windows machine..:wink:

Today i tried to reproduce the problem.. If i get same problem
i define it as a bug..
