I actually have a problem, which was present with 6.17 when I upgraded from 6.15. I have a single IPSec tunnel that's bouncing up and down constantly on 6.17+. It'll be up 10 minutes, down 20, up 15, down 30, up 5, down 10... Seems to be no rhyme or reason to why it's up or down. 6.15 was stable. No...
