Well I overlooked the 6 in ip6tables-resto and blamed it on selinux.  Mr. Walsh added it to the policy to fix the other selinux error, but the machines on the DHCP server get ip's, dns and all and cannot surf so I easily blamed it on selinux.  Sorry for that.  What else could be interfering here?

Here's output of tail -f /var/log/messages:

Sorry but I overlooked the 6 in the selinux denied avc.  Does it make a difference with the server?  

Thanks,
