FWIW, I've revisited this in 13.1-RC1 on my router and was able to successfully
put my router configuration into a jail by allowing the jail to have direct
access to the WAN and LAN ports (the jail host has six GbE ports total, so it
runs management services on a third port).

I was also able to get the separate wireless subnet into the same jail after
putting wlan0 into the jail and tweaking hostapd's rc.d script to allow running
in a jail.

So far, the only issue noticed, which appears to be benign, are these messages
in dmesg when the jail is shutdown or restarted:

[nhop_ctl] inet.0 nhop_free: failed to unlink nh#3/inet/em0/resolve
[nhop_ctl] inet.0 nhop_free: failed to unlink nh#2/inet/em0/<ISP IP address>
[nhop_ctl] inet.0 nhop_free: failed to unlink nh#5/inet/em1/resolve
[nhop_ctl] inet6.0 nhop_free: failed to unlink nh#5/inet6/em1/resolve

If those messages are not an issue, I'd say this bug can be closed.
