I apologize: I have not yet tried to create a simpler test case. If the jail uses unbound on the host for DNS, DNS works. If the jail uses an off-host solution (e.g. my gateway), DNS does not work. When configured to use off-host DNS, and it is failing, the following chang= e to the cloned NIC allows DNS to work: `sudo ifconfig epair47a -txcsum` I'm happy to create a more simple solution and test. The host is question is not used for anything else at the moment. --=20 You are receiving this mail because: You are the assignee for the bug.=
