New page

First of all restrict the data transfer in a defined range of ports, on the ftp server:

Edit the file proftpd.conf and add or modify the following line:
<pre>
PassivePorts 49152 65534 # 49152-65534, the IANA-registered ephemeral port range
</pre>

Now the iptables configuration file should be edited to allow connection on the above port range. Edit /etc/sysconfig/iptables:

<pre>
[root@bpd etc]# cat sysconfig/iptables
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter

:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
