Although this is more of a SecurityBasics topic, in theory couldn't you just set up a telnet program/daemon/whatever (atleast on a windows box, I would think) you could just define that your ftp box or telnet box is ON port 80. From there just telnet to your computer on port 80 (which would be allowed through the firewall) and you'd get access like normal to your desired computer. Thats my question atleast, is that possible? (To tell the daemon to listen (like telnetd) on port 80 instead of 23?) --I know with lots of ftp sites they sometimes pick oddball ports to listen to, is that the same with *nix? (most of these ftp programs that are on odd ports I've seen are windows based). And to further answer the original posters question, if your talking about can YOU from YOUR box get out on another port and somehow bypass the firewall, most likely not. I think even if you set your proxy differently you'd still be going THROUGH the firewall which is the blocker anyway, so you can't really setup YOUR PC to do this, you'd have to have a PC on the outside to go to through an accepted port and from THERE you can go wherever you want to.

well u can setup a redirector outside of your network in the Internet that accepts connections in port 25 or port 80 and redirects you to any other port in any other place. I am not sure if there are any "anonymous" ready to use redirectors like this in the internet but it s very easy to set up one if u have a machine in the internet with administrative access to it.

I have got a question: Is there any possibileties of braking usable ports limitation, what i mean
is My company has instaled proxy that will not put me throught any
other port than 80 and 25. Is there still any possibilety of use telnet
ftp (on their own ports) ?
