Do you utilize PF as your firewalling platform, because I'm slightly suspicious that could be the cause. In fact, it's a bit silly I haven't disabled it entirely to see if that resolves my issues. I'll probably run tests doing that tomorrow and will report back. PF did undergo a lot of changes as I understand it between 9 and 10. On 4/14/2014 9:14 PM, Eugene M.
