Hi Daniel.
06 Dec 25 09:38:02, I wrote to you:
looks like a firewall /port forward issue:
rooniPro15-touchbar-wlan:~ danielp$ telnet rbb.homeip.net 3141
Trying 37.219.0.32...
telnet: connect to address 37.219.0.32: Connection refused
telnet: Unable to connect to remote host
Correct. The port 3141 (tcp/udp) is now closed from the internet. It was open during the tests.
I still wonder why the ivm/3141 connection works inside my lan from one os/2 computer to another. Even with SIO2K, which I installed to another one. Maybe some other ports needed than 3141...
Ok, it is open again. Feel free to test. :)
