Docker: Troubles with telnet

Question

I have trouble with connection to a remote host from a docker container, but if I run that command from the OS cmd it connects normally.

Inside docker container I run command:

telnet address port

And I have seen that DNS works, and resolve right address

` Trying xxx.xxx.xxx.xx

`

And it's not connected to a remote address, after 30 seconds it disconnects of course.

I use:

• MacOSx Monterey Version: 12.3.1 with APPLE M1 chip
• Docker Version: 4.7.1

The same schema can work in the window machine of my colleague. I have tried to find a lot of what should be a reason, but can't find an exact answer to solve this issue, so in the end, decided to ask here.

Thanks
