How do you mean invisible to the gateway. Are you saying you cannot ping them from the gateway?

Can I have some basic configs please:

Also the result from:The result should be no response. Clt+c to stop it.

Please put the results between code tags (the piece of paper icon with a <> on it).

Yes, that was what I explained before when I said "invisible". The jails cannot be pinged from the gateway, and vice versa. I could port forward all I wanted, and nothing would be getting through. Meanwhile other devices were able to ping the jails without issue.

Unfortunately I got tired of this and I installed pfsense on the box this morning. I don't like the admin interface and I haven't figured it all out yet, but I can confirm that this issue doesn't exist. The jails and pfsense can see each other just fine, and Transmission on the FreeNAS box is running happily now, just as it was with 5.2. The issue obviously was with ClearOS 7, or at least it was with the way it got configured by default on my install.

I'll come back to this thread if I decide to give ClearOS another shot.
