2015-09-24 Thread Tommy Pauly
Hello all, Based on the conversation on the IPSec list previously about supporting Split DNS in IKEv2, Paul and I have written up a draft to add support for Split DNS (as well as DNSSEC) to the configuration attributes for IKEv2. We’d like to get feedback from the working group about the level
