Problem is solved anyway. It was a firewall problem.

A firewall problem it was. Solved. Thanks! :) And sorry, the IP was 192.18.212.124. I had earlier temporarily connected to the 209 subnet for testing.

Sorry, it's actually 192.18.212.124. I got it confused after I had connected it to 209, for trying out a different possibility. When trying telnet 192.18.209.124 22, the command prompt just shows SSH-2.0-OpenSSH_5.3 and remains stuck at that

I had even connected the RHEL system to the 209 subnet, where it got a different IP of 192.18.209.17 but I still wasn't able to connect to it using Telnet, but ssh worked as usual.

I agree, but note that the Windows system is 212 and still isn't able to connect. I was able to connect from RHEL to a switch at 192.18.209.111 because in the switch configuration I changed the security setting to allow the RHEL telnet client to connect to the switch. Is there any way to tell the RHEL telnet server to allow other systems to connect to it? I'm able to connect to localhost on the RHEL system.
