yeh i just recently got interested in starting an FTP server... the reason is i just wanted to share files with my friends and what not... yeh but im using the program "Serv-U' one of my friend recommended it because it is very easy 2 learn... but yeh my only prob is getting people to connect without having 2 disable my firewall..... im running windows 2k3 server... and i configured the built in firewall on thier to allow FTP connections but my other firewall im running is Norten Firewall 2002 and im trying to figure out how to configure it... im going through the configuration and like i set it to allow FTP on port 21 [wich is the port Serve-U is using] so now i have options of allowing TCP , UDP , TCP and UDP , or ICMP... and im just wondering wich of these is necesarry for my FTP server to operate correctly.
