Remarks

Address translation using source NAT is performed behind the firewall;
consequently, the physical addresses must be used here.

Destination NAT has already been performed before the firewall; consequently,
the translated addresses must be used here.

The "Trans.Destination IP Subnet" columns in the SCALANCE S615 may only
be configured with a single IP address – /32. Only then does the SCALANCE
S615 reply to ARP requests for the additional IP addresses.
