you have forwarding enabled?
eth0 is your external interface?
all other tables and chains are empty and their policy ACCEPT?
sorry i made a mistake when i have done the copy/past, in the right
rule, it's without the "-o eth0"
in fact it try to contact the web server but there a time-out and it
said it can't contact the web server
with and without the firewall it's the same
I try this (no firewall):
# iptables -A FORWARD -j ACCEPT
# iptables -A OUPUT -j ACCEPT
# iptables -A INPUT -j ACCEPT
# iptables -A PREROUTING -t nat -p tcp -d IpAddServer --dport 81 -j DNAT
--to-destination 192.168.0.2:80
# iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere
Chain FORWARD (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere
yours,
peter
