Hi,
I have these rules below to enable:
a) http port-forwarding in requests b) masquerading rules for http replies.
It does seem to work OK but is very slow. After hours of looking I think the problem as to why it is so slow may be in my Iptables rules.
Can you see a double up or something that may cause a problem ? Or would you say it all looks fine and my problem is elsewhere ?
Thank you ..
$IPTABLES -P INPUT DROP $IPTABLES -P OUTPUT DROP $IPTABLES -P FORWARD DROP
# http requests:
# Port-Forwarding setup
$IPTABLES -t nat -A PREROUTING -i $ETH0 -p tcp --dport 80 -d 66.xxx.xx.100 -j DNAT --to 192.168.0.10:80
# http replies: # ENABLE NAT echo "1" > /proc/sys/net/ipv4/ip_forward

$IPTABLES --table nat --append POSTROUTING --out-interface $ETH0 -j MASQUERADE
$IPTABLES -A FORWARD -i $ETH1 -j ACCEPT
$IPTABLES -A FORWARD -i $ETH0 -j ACCEPT
$IPTABLES -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT
