Problems :telnet with firewall

[yang @ cernet . edu . cn (Yang Jia Hai)]

Hi, gentlemen,

I'm a beginner at firewall. These days, I ftped a public domain of Firewall,
which maintains by Trusted Information System, Inc..

I've installed it successfully. But as I configured it. The permit/deny
mechanism for ftp is OK, but it doesn't work for TELNET. Although I put
a permit rule for a specific host, this host just can't log into my firewall
station. It seems that it just deny everything?!!

Does anyone give me a clue?  Any suggestions would be appreciated.

Thanks in advance.
