nat and slow ftp

nat and slow ftp

[it clown]

Hi All,

I would like to know if the following is the correct way to
setup my firewall rules to browse the net:

iptables -A OUTPUT -p tcp -o ppp0 --dport 53 -j ACCEPT
iptables -A OUTPUT -p udp -o ppp0 --dport 53 -j ACCEPT
iptables -A OUTPUT -p tcp -o ppp0 --dport 80 -j ACCEPT
iptables -A OUTPUT -p tcp -o ppp0 --dport 20 -j ACCEPT
iptables -A OUTPUT -p tcp -o ppp0 --dport 21 -j ACCEPT
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j
ACCEPT

iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

I am using this with squid and it is working.

Is that a good way of doing things? I am nating the ports
right?

What i find is that when i browse ftp site they take ages
to display the contents. Why is this happening and i did
load ip_nat_ftp and iptables_nat.

But when i setup a forward rule for ftp it will connect
nice and quick.

Thanks
Regards
