So no response even in five minutes?

Still looks like a firewall issue to me. Can you telnet to a few things:-
Code:
telnet 10.1.20.33                    # Simple telnet
telnet 10.1.20.33 21                 # FTP port
telnet 10.1.20.33 25                 # SMTP, just as a test
telnet 10.1.20.33 123                # Hit the time server
telnet 10.1.20.33 99999              # Pick a port that should not respond

They should either connect or fail. Try pressing ENTER a few times. You can monitor their success from another session with netstat -na | grep 10.1.20.33 21 to see if the session is established.

Some may never connect, but you should wait at least 60 seconds before cancelling them.

What do you get?

If you are running Linux on either side, are you also using SELinux? That is know for odd errors unless you get it right, and i don't know how.

NAME
telnetrc, .telnetrc - Specifies setup commands for a telnet session SYNOPSIS
$HOME/.telnetrc DESCRIPTION
The .telnetrc file contains the setup information for a telnet session. It is a hidden file in your home directory and must be readable by the user logging in. The file can consist of multiple entries for each remote host to which a user can connect. A remote host entry consists of multiple lines. The first line is the name of a remote host. The subsequent lines must begin with blank spaces, and contain telnet subcommands. These sub- commands are processed as though they were typed in manually. Lines beginning with a number sign (#) are comment lines. See telnet(1) for a complete list of telnet subcommands. To specify subcommands that apply to all systems, create an entry, using the word "DEFAULT" as the system name, and specify the telnet sub- commands in the subsequent lines. EXAMPLES
The following shows a sample .telnetrc file: # Beginning of telnetrc file # Default subcommands that apply to all systems DEFAULT environ undefine USER # First system entry system1 set echo toggle crlf # Second system entry system2 set echo mode line toggle crlf FILES
User-customized telnet startup values. RELATED INFORMATION
