Iv'e got a situation.on my workplace, i'm trying to set up a fileserver using vsftpd on a debian netinstall machine.locally everything works, but from any other location (like eg. My home) i cannot do 'ls'something like this:ftp ls500 illegal port commandftp: bind: Adress allready in usethe port is set to 1028, ftp-data is set to 1027. Both forward (router NAT) to the correct system, and i've set up this:pasvmin=1030pasvmax=1035all these ports are forwarded correctly, but still passive does not work (my server simply does not recieve the passive connections if i do 'netstat -a'i've been looking everywhere, including on this forum but i cannot find a (working) solution.basicly, on the local LAN, everything works just fine.but from the moment i have to pass the router, i cannot get a directory listing in any way.i.think.
the problem must be in the router somewhere. Is it possible that some routers cannot do NAT correctly? Or did i simply miss something?i've allso tryed to copy the vsftpd.conf file to my private fileserver, and set up the NAT in my router just about the same way i did on my workplace, and then everything works fine.if you need more information about this problem, simply ask. From your home, are you connecting passively to the ftp server?

Are you running any sort of firewall on the server itself? What type of nat translation is the router doing (i.e. A 1-1 nat translation - ip nat inside source static, and are you specifying ports in that statement)?I remember trying to solve a problem similar to this, and it was a router problem.
The statements in the acl permitting the traffic were below an explicit deny ip any any statement on a cisco router.You may want to try disabling the external firewall, or allowing all traffic to pass through your router temporarily to see if that solves your problem, then you will know whether or not it is an external router/firewall issue.Also, see if some of the suggestions at are of any help. Well, both passive and active connections fail.i get the mentioned error with active connection, with the passive connection he try's to initiate (the client) but the server never recieves the request.
(none of my logfiles show any passive connection (attempt) or anything having to do with this.i can however see the login in my logs.i've set these rules in my vsftpd.conf:tcpwrappers=YESlistenyeslocalenable=YESanonymousenable=YESwriteenable=YESconnectfromport20=NOftpdataport=1027ftplistenport=1028pasvenable=YESpasvminport=1030pasvmaxport=1035in my router, ports 1027 to 1035 are forwarded to my local serverunfortunetly, i do not entirely get what you mean with. Have you double checked the rules that are applied with the tcpwrappers=YES option enabled? I think the best thing to try is to disable any sort of filtering when connecting from the outside to see where the problem is, i.e.
Turn off filtering on the router (or allow all ports to and from your server ip) and try to connect, if you get the same result, put it back on. Turn off filtering from iptables, if same result, put back on, etc. Then at least you can find out where exactly the problem is occuring.When I say:What type of nat translation is the router doing (i.e. A 1-1 nat translation - ip nat inside source static I am mainly asking how is the nat translation being implemented. I guess this would be better to start off by asking what type of router you are using, as I am using cisco commands because this is what I am used to.
You can specify nat translations to only occur when a specific port is being requested if you specify a tcp connection.
The problem I'm experiencing is that I'm getting a '500 Illegal PORT command' Response from an FTP server when attempting to upload a file programmatically.This program is a small c# application that connects to an FTP site and copies files to the default directory. This program has been in production for several years and I am confident the code itself works just fine. I've also tested the application by connecting to my own FTP site using the same application and it works. Passive mode does not seem to be an option.When attempting to connect to our partner's FTP site, the program runs as expected until the FTP put command is executed. I have noticed when running Wireshark that the source IP of my Request is different from the IP address the PORT command is sending.
I have uploaded an image of a capture here (all sensitive information has been removed using my amazing photoshop skills).I have contacted the owner of the FTP site where we are attempting to transfer the files and they have opened their firewall for our new Static IP address. I can connect to their site using FTP clients from machines on both of the LAN IP's, but those PORT commands are always sent using the same LAN IP as the source of the request. I have also tried using ftp.exe from the server where the program resides, and it is successful (but the PORT command uses the same IP as the source).So I guess the big question is how can I control what IP address the PORT command uses? Ibm t41 drivers windows 7. Or, if I can't control it, how is the IP address and PORT determined by the ftp program?
