thats a god point..and then...with the actual config....( i filter the ports that the firewall trys to reach on remote machines..so they can't conect to ftp ot telent..or anything fiferent to 80.....)that any one could do a tunneling?¿ ( appart form teh one you allready told me....)
They only way to access things like ftp, telnet, etc would be through a tunnel. Otherwise, it's possible that you've got it locked down. That said however, do NOT assume it's 100% secure. There are always ways around things. Nothing prevents them from downloading through port 80. You are blocking based on port not application.
thats true......i sould be monmitoring also aplications in teh network that acces to teh outside world.....jajaja haven't think on taht....
jejejej don't know if tihis a dumb kuestion....you can anyhow configure a server...said ftp.....to use an interpeter so it could get http like request?¿
teh point if theres any way tah anyone could be getting conected to outside perosnal server.....but looking like it was just a http request to a web page?¿
Only if it's running a web server on it or some other application. Someone could use telnet or netcat to create similar access to a web server. But again, it's if the ftp server is running a webserver.
that's all for today...thanks a lot......i'll check all you told me..and the i'll came back with more questions......
faith_in_death, you might want to read this article on HTTP Tunnelling. It might add a little more for you to be concerned about.
