CentOS - Dec 2007 - Regd: Iptables Source NAT

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.

192.168.13.83 does not look like an ipv6 address.

I would like to help, but i honestly did not understand the problem.
If possible, please elaborate.
