Re: ftp slow with iptables

Sounds like the old "reverse DNS lookup" problem.

Hello,

On my FC3 machine I run a FTP server (vsftpd). I also run a firewall (iptables).

I add a rule to my /etc/sysconfig/iptables file:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT

 

From my Windows box, I use WS_FTP to connect and all is well….except for the speed of connection. When I turn the firewall off, I can connect within milliseconds. However, when I turn the firewall on it can still connect but it can take up to 20 seconds to make a connection and give my directory listing.

 

Any ideas?

 

Thank you!
