IP address assignments to jails using ezjail

[James B. Byrne]

I am experimenting with jails on a bhyve vm guest running FBSD-11.0
using ezjail.  I am having a problem with network connections to the
outside from within the jail.  I have sshd configured and I can reach
the jail from the outside:

$ ssh -vv 192.168.216.196
OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to 192.168.216.196 [192.168.216.196] port 22.
debug1: Connection established.

But inside the jail I cannot connect out:

ssh -vv 192.168.216.22
OpenSSH_7.2p2, OpenSSL 1.0.2j-freebsd  26 Sep 2016
debug1: Reading configuration data /etc/ssh/ssh_config
debug2: resolving "192.168.216.22" port 22
debug2: ssh_connect_direct: needpriv 0
debug1: Connecting to 192.168.216.22 [192.168.216.22] port 22.
debug1: connect to address 192.168.216.22 port 22: Operation timed out
ssh: connect to host 192.168.216.22 port 22: Operation timed out


On the host system I see this:

# ifconfig
vtnet0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST>

        options=80028<VLAN_MTU,JUMBO_MTU,LINKSTATE>

        inet 127.0.1.1 netmask 0xffffffff

        groups: lo
pflog0: flags=141<UP,RUNNING,PROMISC> metric 0 mtu 33160
        groups: pflog

Inside the jail I see this:

root at hlldrupal:~ # ifconfig

        options=80028<VLAN_MTU,JUMBO_MTU,LINKSTATE>

        groups: lo
pflog0: flags=141<UP,RUNNING,PROMISC> metric 0 mtu 33160
        groups: pflog


Any ideas as to what I may have failed to do?
