Must be DNAT or SNAT\&.
.sp
If DNAT, traffic entering INTERFACE and addressed to NET1 has it\'s destination address rewritten to the corresponding address in NET2\&.
.sp
If SNAT, traffic leaving INTERFACE with a source address in NET1 has it\'s source address rewritten to the corresponding address in NET2\&.

The name of a network interface\&. The interface must be defined in
\m[blue]\fBshorewall\-interfaces\fR\m[]\&\s-2\u[1]\d\s+2(5) Prior to Shorewall 4\&.1\&.4, this must be an exact match\&. Shorewall\-perl 4\&.1\&.4 and later allow loose matches to wildcard entries in
\m[blue]\fBshorewall\-interfaces\fR\m[]\&\s-2\u[1]\d\s+2(5)\&. For example,
\FCppp0\F[]
