# bastille rdr --help
Usage: bastille rdr TARGET [clear] | [list] | [<interface> tcp <host_port> <jail_port>] | [<interface> udp <host_port> <jail_port>]
Usage: bastille rdr TARGET [options(s)] [clear|list|(tcp|udp host_port jail_port [log ['(' logopts ')'] ] )]
Options:
-i [interface] | -- Set the interface to create the rdr rule on. Useful if you have multiple interfaces.
-s [source ip] | -- Limit rdr to a source IP. Useful to only allow access from a certian IP or subnet.
-d [destination ip] | -- Limit rdr to a destination IP. Useful if you have multiple IPs on one interface.

If you have a host with multiple interfaces, and you want to specify which
one to use, `bastille rdr` allows you to pass any interface to the command.
If you do not specify an interface, the default one will be used.
Bastille included 3 options for the three following scenarios.
- Setting a non-default interface on which to create the rdr rule.
- Limiting the source IP on the rdr rule.
- Limiting the destination IP on the rdr rule.

# bastille rdr dev1 list
rdr on em0 inet proto tcp from any to any port = 2001 -> 10.17.89.1 port 22
rdr on vtnet0 inet proto udp from any to any port = 2053 -> 10.17.89.1 port 53
rdr pass on vtnet0 inet proto udp from any to any port = 2001 -> 10.17.89.1 port 22
rdr pass on em0 inet proto tcp from 192.168.0.1 to any port = 8080 -> 10.17.89.1 port 81
rdr pass on em0 inet proto tcp from any to 192.168.0.84 port = 8082 -> 10.17.89.1 port 82
rdr pass on vtnet0 inet proto tcp from any to 192.168.0.45 port = 9000 -> 10.17.89.1 port 9000
The options can be used together, as seen above.
