Jail's network binding lost when router restarts

[czettnersandor]

I had to restart the router and noticed the jail is inaccessible from the outside. When I log in to NAS4Free, TheBrig shows something unusual. The Status reads "Stopped", but the Action button is "Stop". jls shows the jail didn't stop. The same is happening when I pull out the network cable and plug in back again.

From inside the Jail, dmesg:

re0: link state changed to DOWN
re0: link state changed to UP`

host's ifconfig after the restart:

re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=8009b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LINKSTATE>

(note the jail's IP address is missing)

The jail is still running regarding jls:

$ jls
   JID  IP Address      Hostname                      Path
