hi,

I just wanna know few things , i have installed red hat 9, iptable = is=20 installed.

Now the thing is, i didnt know at first = that i have=20 to load the modules, i was getting the message

iptables: No chain/target/match by that name

so after couple of searches i did find = some help=20 and i manage to apply few commands i.e.

modprobe ip_tables
modprobe ip_conntrack
modprobe=20 iptable_nat
modprobe ip_conntrack_ftp
modprobe = ip_nat_ftp

iptables=20 -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD=20 DROP
iptables -A INPUT -p icmp --icmp-type 8 -j DROP

all the above commands are accepted at command prompt, but when i = try to=20 use this command

iptables -A PREROUTING -s=20 xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy -p tcp -m tcp --dport 80 -j REDIRECT = --to-ports=20 8080 where xxx is any IP and yyy is the subnet mask, it returns me the = same=20 message i.e.
iptables: No chain/target/match by that name

So = it also=20 give the same message with POSTROUTING.

also i dont wana load = the=20 modules and the commands each time the system starts, so when i type the = commands i used iptables-save command to save tat, also is there ne = possibility=20 where i can store the command and execute when system=20 startsup
