I have been having some intermittant problems using ftp on various computers. We have a cisco router. It will connect t the site, but then the problems start. In active mode, it gives the error 425 can't open data connection when doing MLSD. When using pasive mode, it gives a 421, can't create socket and then a timeout. Not sure if this is a router issue, but if I use an air card with the same computer, it works fine. It also works fine on another network. The computer is running windows xp and we are using filezilla. We also tried the comand line and it hangs when doing a directory listing. Any soggestions on what is wrong or how to troubleshoot this. We finally have a duplicatable situation. I enabled logging on the router and nothing is blocked.

It is 1500. Not sure on the air card, that computer is not here right now. This problem is al across our network. Is there a way to debug and see what is happening?

Another note, it is not all ftp sites, only certain ones in certain situations.

Check your windows xp firewall. Make sure you allow FTP and FTP-data ports through.

I have not used wireshark, please advise on what I should do.

Firewall is turned off and the ftp works through other connections and does not work on other machines through this connection.
