SNAT & DNAT

[Marvin]

I am having much trouble trying to make this work.  On an older system it was quite easy.  On OPNsense i am very confused.

I have 2 IPSec tunnels.  These two tunnels route traffic directly between each other.  There is no local LAN configured, only the WAN which supports the IPSec tunnels.

I have some SNAT's and some DNAT's and some 1-to-1 NATs that make everything work (on the older system).  They all attach to IPSec.  But SNAT and DNAT do not appear to be part of the OPNsense vernacular.

OPNsense uses Port Forward, Outbound and 1-to-1 NATs.  But which are SNAT and which are DNAT?
