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 did not think I was blocking any outgoing connections so passive mode should work. Obviously I am in error. We are doing nat. Here is some of my script:
interface FastEthernet0/0
 ip address xx.xx.xx.xx 255.255.255.240
 ip access-group outside_in in
 ip nat outside
 ip virtual-reassembly
 duplex auto
 speed auto
!
interface FastEthernet0/1
 ip address 192.168.1.5 255.255.255.0
 ip nat inside
 ip virtual-reassembly
 duplex auto
 speed auto

Any suggestions on what to look for?

Unfortunately Cisco is not my forte... :(

However this is how a passive connections looks like when active (follow the arrows):
