problems using telnet

["sunil bachwal" <bsunil9@xxxxxxxxxxx>]

Hi,

  I had installed squid2 and configured it as internet sharing proxy.

  The problem is, the users behind the squid proxy are not able to telnet 
to my mail server.

 For example is users behind telnet give a command as follows

  > telnet 202.54.37.xxx

  they receive an error like "Could not open connection to the host on port 
23: connection failed"

in squid.conf i had set " ftp_telnet_protocol on ", but that doesnt seem to 
wok and i have no firewall installed.


please help me.

thanks in advance
