ftp from msdos
 

Hello all.
I'm having a problem with ftp from a custom system at a client that uses ftp to get som files from suppliers.
The new firewall is obviously stopping it as it wasn't a problem before.
I've tried ftp-connections with firefox, msie, smartftp and lftp and they all work, the only place I can replicate the problem is with the ftp-client in dos (or windows cmd).
I've allso tried purging all rules and setting policy to accept on all chains, still the same problem...
Anyone have any good ideas?

If you do: Thanx a lot, I'm stuck...

ps. ip_conntrack_ftp is loaded, allthough I don't think it should matter when defaulting to ACCEPT

ip_conntrack_ftp and ip_nat_ftp are used for active ftp to allow the data channel on port 20 to be handled correctly..

It's time to start looking more closely at the individual packets, prob with tcpdump.
Have a look at man tcpdump and the examples later in the page.

Make sure replies are returning correctly.

The programme wget exists for M$ so you can use some of it's passive/active options to test with.
