Hi folks, I am running Linux 2.4.20 on my router with LAN IP FILTER rules as - Allow from LAN to WAN on port 21 Deny all from LAN to WAN Now, when I ftp to a machine on the WAN Only the control connection opens ( Login is fine), but the data connection does not open. The machine freezes when I do an "ls".. I am using passive ftp here. When I put printk's in the code, the expected is added, the CT is formed and NF_DROP does get called at any stage Kindly Help!!!
