Quoting Johnny Hughes johnny@centos.org:
If you currently have to change the config file and recompile the kernel, tell me the config items you are turning on and I will see if I can roll them into the new CentOSPlus kernel.
Hmmm... I recently had a need to test one of the "standard" Netfilter modules, just to find out it wasn't part of any CentOS kernels (base or centosplus). If it is possible, could you add ROUTE module? Not sure if this is standard part of kernel source, or patch-o-matic(-ng) is needed. The userland iptables might also need to be rebuilt and placed into centosplus.
Anyhow, it would be nice to have support for all "standard" targets/extensions that are documented in "man iptables". If it is not too much trouble to include them. ROUTE is one of them. I see couple of others that might be usefull to have (not that I currently have need for all of them) such as BALANCE, CLASTERIP, CONNMARK (it would simplify some stuff I'm doing), NOTRACK, ROUTE... Probably some others. Userland iptables already includes some of them, but not all, so it would also need to be included into centosplus.
