Github user kiwiflyer commented on the pull request: https://github.com/apache/cloudstack/pull/1478#issuecomment-207524802 PR https://github.com/apache/cloudstack/pull/872 is going to replacing openswan with strongswan. I believe PFS is depreciated in strongwan, so it might make sense to just remove PFS once 872 is committed. It might be worth while looking at addressing this just in 4.7.x and 4.8.x. Thoughts?
