Second Jail looses connectivity

Hello :)

I have an issue where every jail (except the first jail I ever created) looses connection to anything besides the truenas (core) server itself. For me it looks like it looses connection to the gateway, but I might be wrong with that assumption.

My configuration is:
NIC: Intel X540-T2 -> bonded to failover
Ifconfig:

Code:

For testing I also activated DHCP (no change). I also created a third jail for testing. That jail also looses connectivity after 30-60 minutes. Sometimes faster sometimes slower. I created the jails exactly the same way.

Is there anything I am missing?

I guess I did a bad job explaining what happens :D
So after 30-50 Minutes:
  1. I still can ping the jail from inside my network
  2. From inside the jail (iocage console) I can't ping google
  3. From inside the jail I can't ping the gateway/dns etc.
  4. From inside the jail I can ping TrueNAS
All this only happens on jails that are not the first jail I ever created. The order of which I start the jails doesn't seem to matter. I don't have any IP conflicts.
I use the current release TrueNAS CORE 12.0-U2
