how to configure host login account to use jail?

[Fbsd8]

Have jails up and running on host with ip address of
10.0.10.10 10.0.10.11 10.0.10.12 10.0.10.13 10.0.10.14
The host rc.conf has
ifconfig_xl0="DHCP"  # nix connected to isp
ifconfig_rl0="inet 10.0.10.2"  #lan nic

I want lan users to login to their jail by ip address using ssh.
How do I setup host user accounts so they login to
their associated jail?
Is this something I code in the host user account or is it done
by the remote ssh login command?

How do other jail users do this?
