# # Shorewall --/usr/share/shorewall/macro.template # # Macro files are similar to action files with the following exceptions: # # - A macro file is not processed unless the marcro that it defines is # referenced in the /etc/shorewall/rules file or in an action # definition file. # # - Macros are translated directly into one or more rules whereas # actions become their own chain. # # - All entries in a macro undergo substitution when the macro is # invoked in the rules file. # # Columns are the same as in /etc/shorewall/rules. # A few examples should help show how Macros work. # # /etc/shorewall/macro.FwdFTP: # # #ACTION SOURCE DEST PROTO DPORT SPORT ORIGDEST RATE # DNAT - - tcp 21 # # /etc/shorewall/rules: # # #ACTION SOURCE DEST PROTO DPORT SPORT ORIGDEST RATE # FwdFTP net loc:192.168.1.5 # # The result is equivalent to: # # #ACTION SOURCE DEST PROTO DPORT SPORT ORIGDEST RATE # DNAT net loc:192.168.1.5 tcp 21 # # The substitution rules are as follows: # # ACTION column If in the invocation of the macro, the macro # name is followed by slash ("/") and a second # name, the second name is substituted for each # entry in the macro whose ACTION is PARAM # # For example, if macro FOO is invoked as # FOO/ACCEPT then when expanding macro.FOO, # Shorewall will substitute ACCEPT in each # entry in macro.FOO whose ACTION column # contains PARAM.
