Ok first off...

Im trying to setup a FTP Server on my linux machine that im using as a HTTP server and a router.

Im using VSFTPD as the FTP server and i cant connect to it. A friend told me to try TELNET or something and that failed. (I think it was in console telnet 21)

Onto the forwarding. Im trying to forward any given port to 192.168.0.5:80 As im trying to run a webserver on linux and one on my Windows PC so i dont have to keep updating files on each and i can just type xxx.xxx.xxx.xxx:PORT and it will forward to my windows files that are up to date.

Ive tried masquerading etc and no use there.

Im really confused here

The description of your goal is unclear. It sounds like you are trying to make a web site and want to see it happening on IIS and Apache, is that correct? If this is the case, you can install Samba on the Linux box and make the share show up in the web server, with a symbolic link perhaps. Then map the share to a network drive letter on the Windows box and make that drive a Virtual Folder in IIS. You'll have one directory that both feed off of.

Problem 1)
What i have is 2 machines


Linux (acting as the internet server, firewall, router and a webserver)
Windows (my pc with XAMPP on it)

I want to be able to forward any port to my windows PC but i dont know how to.

Problem 2)
I have a VSFTPD installed on my linux machine and it doesnt allow me to connect. It doesnt say anything about passwords it just says unable to connect.

for problem 2:
run netstat -an and see if tcp port 21 is LISTENING, if not, it means ftp is not started at all. if yes, try this:

telnet localhost 21
or,
ftp localhost

and login with a shell user name:

user crazerkiller
pass XXXX

this should bring you to the home directory

Using telnet 21 i get

"> telnet localhost 21
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host."

And ftp localhost

"> ftp localhost
Trying 127.0.0.1...
Name (localhost:root):
EOF received; login aborted."

Ive probaly done the ftp part wrong but hey new to linux CMD line

For problem 2...

1. service vsftpd status
service vsftpd start
service vsftpd restart
( commands for ftp service status n restart)

2. vi /etc/vsftpd/vsftpd.conf --> configuration file for vsftpd

3. vi /etc/vsftpd.ftpusers --> comment the users which you want to log into ftp server

4. vi /etc/vsftpd.user_list --> comment the users which you want to log into ftp server

5. ftp <local-ip>
enter user-name & password.
( running ftp)

For problem 1...

For packet forwarding... You need to
echo 1 > /proc/sys/net/ipv4/ip_forward

This enables packet forwarding.. n after that you need to use IPTABLES for port forwarding.
For that google it appropriately.

for security reasons, ftpd does not let root to connect to it directly, please try another general user.

Ok that was the reason why lol i was connecting through root so it didnt allow it

Yes by default root is not allowed to make FTP connection..but you can change this (not suggestable). Just modify the file '/etc/vsftpd.ftpusers' and remove the entry by name of root.

About your first issue I think you are looking something like 1:1 NAT. So for that you can use 'iptables' with DNAT.

I dont know anything about DNAT NAT or Iptables :S
