ipchains can handle that. Look for something like
"ipchains-1.3.8.tar.gz" in tarball format; the RH site probably has an
RPM format available for download. The HOWTO in the documentation will
tell you just about anything you need to know about how to implement it.
It lets you set policy for input, output, etc. You can then chain rules
together to accept or deny access by protocol, port number, interface,
etc. In other words, you can set a policy to deny all input (incoming
connections from the 'net), then add a rule to the input chain that says
if the input is coming to port 80 (http), accept it. That would allow
foreign browsers to connect to your web server, but telnet and ftp
connections would be denied.
