Maybe have a look at Libreswan which was forked from Openswan 2.6.38. It has a ton of bugfixes and patches over Openswan and there is an EL6 repo which should work on CentOS6 too. More info: http://libreswan.org https://download.libreswan.org/ https://github.com/libreswan https://lists.libreswan.org/mailman/listinfo https://twitter.com/libreswan #swan IRC channel on FreeNode AFAIK one the of the main developers and driving forces behind Libreswan is employed by Red Hat so it would not surprise me if Libreswan were to replace Openswan in EL7.
