Hi, I know this isn't strictly an ISPConfig 3 question - but my problem is on a box which is set up according to the The Perfect Server guide for Debian (http://www.howtoforge.com/perfect-server-debian-lenny-ispconfig3-p4) - so I thought I might give it a go posting my question here. Basically the problem rests in being unable to connect to FTP from outside of my LAN. Yes, I know the first thing I should check is if my ports are open - and they most certainly are! Let me break it down: 1) I can connect fine locally if I use the servers IP directly from other machines on the LAN (also telnet localhost 21 on the server works fine) 2) I can connect to the server fine externally on other ports, such as 80 and 22 (HTTP and SSH) 3) Ports 20 and 21 are open through to my server But when I try to connect, I get a "Connection Refused" message. 4) I then check to see if pure-ftpd is running - it is. Also, netstat -lnptu gives me: Code: tcp 0 0 0.0.0.0:48064 0.0.0.0:* LISTEN 2051/rpc.statd tcp 0 0 192.168.0.110:9000 0.0.0.0:* LISTEN 4123/twonkymediaser tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 4123/twonkymediaser tcp 0 0 127.0.0.1:5000 0.0.0.0:* LISTEN 4080/rtorrent tcp 0 0 127.0.0.1:10024 0.0.0.0:* LISTEN 2295/amavisd (maste tcp 0 0 127.0.0.1:10025 0.0.0.0:* LISTEN 3740/master tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 2450/mysqld tcp 0 0 127.0.0.1:623 0.0.0.0:* LISTEN 3839/famd tcp 0 0 127.0.0.1:783 0.0.0.0:* LISTEN 2514/spamd.pid tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 2040/portmap tcp 0 0 0.0.0.0:10000 0.0.0.0:* LISTEN 3958/perl tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN 6456/pure-ftpd (SER tcp 0 0 192.168.0.110:53 0.0.0.0:* LISTEN 3666/mydns tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN 3666/mydns tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 2267/sshd tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 3740/master tcp 0 0 0.0.0.0:55998 0.0.0.0:* LISTEN 4080/rtorrent tcp6 0 0 :::993 :::* LISTEN 3643/couriertcpd tcp6 0 0 :::995 :::* LISTEN 3661/couriertcpd tcp6 0 0 :::139 :::* LISTEN 3801/smbd tcp6 0 0 :::110 :::* LISTEN 3649/couriertcpd tcp6 0 0 :::143 :::* LISTEN 3631/couriertcpd tcp6 0 0 :::8080 :::* LISTEN 3898/apache2 tcp6 0 0 :::80 :::* LISTEN 3898/apache2 tcp6 0 0 :::8081 :::* LISTEN 3898/apache2 tcp6 0 0 :::21 :::* LISTEN 6456/pure-ftpd (SER tcp6 0 0 ::1:53 :::* LISTEN 3666/mydns tcp6 0 0 :::22 :::* LISTEN 2267/sshd tcp6 0 0 :::443 :::* LISTEN 3898/apache2 tcp6 0 0 :::445 :::* LISTEN 3801/smbd AFAIK then after setting everything up with the Perfect Server guide then my system isn't using inetd for ftp - so the hosts.allow file shouldn't factor into this - I did add ftpd : ALL : ALLOW to it however to no avail. And no, I am not trying to access the server from within my lan using the external IP (which could result in a NAT loopback problem if my router doesn't support it... Which I actually don't think it does) - I have been using this service to test with: http://www.wormly.com/test_ftp_server So, it looks to me that my Debian box is actively refusing connections on port 21 if it is coming from outside the LAN. What can I do to resolve this? Thanks!
