Question
Setup Iptables for FTP Passive connections Ubuntu?
Hi
I have setup the iptables using the guide https://www.digitalocean.com/community/articles/how-to-set-up-a-firewall-using-ip-tables-on-ubuntu-12-04 and it works great. Now I need to also configure the iptables to allow FTP to use Passive Mode. I have read that you need to run command
#modprobe ip_conntrack_ftp and modprobe ip_conntrack and these 2 are loaded.
The current iptable looks like this.
iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -p tcp --dport ssh -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -p tcp --dport 21 -j ACCEPT
iptables -A INPUT -p tcp --dport 25 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j ACCEPT
iptables -A INPUT -p tcp --dport 2812 -j ACCEPT
iptables -A INPUT -p tcp --dport 10000 -j ACCEPT
iptables -A INPUT -j DROP
Any idea how to allow Passive FTP sessions in Iptables?
Many thanks
Mike
