SHOREWALL6-EXCLUSIO(5)						  [FIXME: manual]					    SHOREWALL6-EXCLUSIO(5)

NAME

       exclusion - Exclude a set of hosts from a definition in a shorewall6 configuration file.

SYNOPSIS

       !address-or-range[,address-or-range]...

       !zone-name[,zone-name]...

DESCRIPTION

       Exclusion is used when you wish to exclude one or more addresses from a definition. An exclaimation point is followed by a comma-separated
       list of addresses. The addresses may be single host addresses (e.g., fe80::2a0:ccff:fedb:31c4) or they may be network addresses in CIDR
       format (e.g., fe80::2a0:ccff:fedb:31c4/64). If your kernel and ip6tables include iprange support, you may also specify ranges of ip
       addresses of the form lowaddress-highaddress

       No embedded whitespace is allowed.

       Exclusion can appear after a list of addresses and/or address ranges. In that case, the final list of address is formed by taking the first
       list and then removing the addresses defined in the exclusion.

       Beginning in Shorewall 4.4.13, the second form of exclusion is allowed after all and any in the SOURCE and DEST columns of
       /etc/shorewall/rules. It allows you to omit arbitrary zones from the list generated by those key words.

	   Warning
	   If you omit a sub-zone and there is an explicit or explicit CONTINUE policy, a connection to/from that zone can still be matched by the
	   rule generated for a parent zone.

	   For example:

	   /etc/shorewall6/zones:

	       #ZONE	      TYPE
	       z1	      ip
	       z2:z1	      ip
	       ...

	   /etc/shorewall6/policy:

	       #SOURCE	       DEST	     POLICY
	       z1	       net	     CONTINUE
	       z2	       net	     REJECT

	   /etc/shorewall6/rules:

	       #ACTION	       SOURCE	     DEST	 PROTO	       DEST
	       #						       PORT(S)
	       ACCEPT	       all!z2	     net	 tcp	       22

	   In this case, SSH connections from z2 to net will be accepted by the generated z1 to net ACCEPT rule.
