Re: problem with pasive MODE and NAT
Try loading two additional netfilter modules to do conection tracking for your ftp conection called "ip_conntrack_ftp" and "ip_nat_ftp" this should sort out your problem Regards Corne Alberts Information Architect Quoting Francisco Castillo <[EMAIL PROTECTED]>: > > Hello, > > I has a proftpd server on a linux debian woody with a NAT sheeme.

problem with pasive MODE and NAT
Hello, I has a proftpd server on a linux debian woody with a NAT sheeme. So my proftpd is listening on the 192.168.0.X private ip and my router has mapping the ports from 4 to 40010 from the public ip to the 192.168.0.X ip in order to allow pasive port transfers from internet. So i has this config on my proftpd.conf # para el NAT MasqueradeAddress 217.00.00.214 PassivePorts 4 40010# These ports should be safe but i has this problem: when i connect from a cuteftp client from a 192.168.0.Y ip the client get the correct pasive port to get data (4) from the proftpd server but if i try to access from a public client ip (with cuteftp too) the server said to get a aleatorious port and not in the range 4-40010 COMANDO:> PASV 227 Entering Passive Mode (217,00,00,214,238,235)). 238,235 = 238*256 + 235 != 4-40010 so i ask what could be happening? How could i solve my problem?
