Hi! thanks for trying it out
I am a little nearer to the problem than I was once before...the issue is to do with the renaming of the iptables modules between kernels - in particular connmark which is used for the protocol filter (which is also broken

). I have attempted to upgrade iptables but this breaks the ClearOS firewall further...unfortunately without patching of the firewall module I don't think i'll have a solution, we'll have to wait for 6.0
Out of interest it appears RHEL6 uses a hybrid mix of 2.6.34 features and previous kernels depending on their stability and relevance to the server market
