Issue

• Why do I see "kernel: NAT: no longer support implicit source local NAT" on RHEL5?

Sample configuration and logs:

[root@rhel5 /]#  service iptables status | tail -4
Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination         
1    DNAT       all  --  0.0.0.0/0            192.168.122.101     to:192.168.122.1 

[root@rhel5 /]# ping 192.168.122.101 -c 1 
...skip
[root@rhel5 /]# tail -2 /var/log/messages
