You only have configured the 192.168.1.84 ipaddr on your nve0 interface,
you need to configure the 192.168.1.85 ipaddr. on the interface too.

Delete the

ifconfig_nve0="inet 192.168.1.84 netmask 255.255.255.0"

line in rc.conf and replace it with

ipv4_addrs_nve0="192.168.1.84-85/24"

and do a reboot. If you don't want to reboot, use "ifconfig nve0 alias
192.168.1.85/32" to configure the alias while the system is running.

You could also use the jail_example_interface="nve0" option in rc.conf
and reboot, but I don't recommend that because it is somewhat broken and
poorly implemented.

greetings,
philipp
