(internal to the router and outer.)  
1. ping from [vbox01] to [vyos01] is OK.  
2. ping from [vbox01] to [hostpc] is Error. (no route.)  
(HostPC to the router and internal nt.)  
3. ping from [hostpc] to [vyos01] is OK.  
4. ping from [hostpc] to [vbox01] is Error. (these 2 network is different.)  
(Router to the hostpc and internal nt.)   
5. ping from [vyos01] to [vbox01] is OK.  
6. ping from [vyos01] to [hostpc] is OK.

outbound nat - route from [vbox01] to [hostpc] (and more).

set nat source rule 10 outbound-interface eth0
set nat source rule 10 source address 192.168.1.0/24
set nat source rule 10 translation address masquerade

⇒2. ping from [vbox01] to [hostpc] is ~~Error~~. - Change to OK!

reverse nat - address forwarding

set interfaces ethernet eth0 address 172.19.1.200/32
set nat destination rule 20 destination address 172.19.1.200
set nat destination rule 20 inbound-interface eth0
set nat destination rule 20 translation address 192.168.1.121
set nat source rule 20 outbound-interface eth0
set nat source rule 20 source address 192.168.1.121
set nat source rule 20 translation address 172.19.1.200

⇒4. ping from [hostpc] to [vbox01] is ~~Error~~. - OK! Translation into internal ip
