All,
I was hoping to use GEOM gate for a project I was working on. But it
appears to be have a few issues. The first of which is a kernel panic
whenever access is denied from ggated. For example:
... this is printed on the ggated host ...
Dec 1 20:05:23 host ggated: Unauthorized connection from: x.x.x.x.
... which leads to this on the ggatec host ...

Is this a known issue?
