Dear All, I am using the following rules in firewall scripts /sbin/iptables -F INPUT /sbin/iptables -F OUTPUT /sbin/iptables -F FORWARD /sbin/iptables -F RH-Firewall-1-INPUT # Default Rule /sbin/iptables -P OUTPUT ACCEPT /sbin/iptables -P INPUT ACCEPT /sbin/iptables -P FORWARD ACCEPT Rsync Source NAT rules is iptables -t nat -A POSTROUTING -p tcp -s 192.168.13.179 --dport 873 -j SNAT --to-source 192.168.13.83:873 192.168.13.179 is eth0 ipv4 ipaddress and 192.168.13.83 is eth0 ipv6 ipaddress The following rules is working fine But the problem is at every rsync trigger we will restart the iptables and firewall scripts, then only it will works If the services are not restart then it will send the following error message "rsync: failed to connect to 192.168.13.100: Connection timed out (110) rsync error: error in socket IO (code 10) at clientserver.c(94)" I need to solve the following "iptables and firewall restart" issue. Can some one throw light on this. Regards -S.Balaji
