Dear Friends,

To enable NAT on my network I have setup this in iptables

echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/iptables --flush
/sbin/iptables --table nat --flush
/sbin/iptables --delete-chain
/sbin/iptables --table nat --delete-chain
/sbin/iptables --table nat --append POSTROUTING --out-interface ppp0 -j 
/sbin/iptables --append FORWARD --in-interface eth0 -j ACCEPT

Every thing is running fine, but sometime MSN messenger get disconnect or 
its take alot time to connect.

So I want to know, is there any mistake in my this script or its my ISP
