hosts - shorewall6 file




This file is used to define zones in terms of subnets and/or individual IP addresses. Most simple setups don't need to (should not) place anything in this file.

The order of entries in this file is not significant in determining zone composition. Rather, the order that the zones are declared in m[blue]shorewall6-zonesm[][1](5) determines the order in which the records in this file are interpreted.


The only time that you need this file is when you have more than one zone connected through a single interface.


If you have an entry for a zone and interface in m[blue]shorewall6-interfacesm[][2](5) then do not include any entries in this file for that same (zone, interface) pair.

The columns in the file are as follows.

ZONE - zone-name

The name of a zone declared in m[blue]shorewall6-zonesm[][1](5). You may not list the firewall zone in this column.

HOST(S) - interface:[{[{address-or-range[,address-or-range]...|+ipset}[exclusion]]

The name of an interface defined in the m[blue]shorewall6-interfacesm[][2](5) file followed by a colon (":") and a comma-separated list whose elements are either:
1. The IPv6 address of a host.
2. A network in CIDR format.
3. An IP address range of the form low.address-high.address. Your kernel and ip6tables must have iprange match support.
4. The name of an ipset.
You may also exclude certain hosts through use of an exclusion (see m[blue]shorewall6-exclusionm[][3](5).

OPTIONS (Optional) - [option[,option]...]

A comma-separated list of options from the following list. The order in which you list the options is not significant but the list must have no embedded white space.
shorewall6 should set up the infrastructure to pass packets from this/these address(es) back to themselves. This is necessary if hosts in this group use the services of a transparent proxy that is a member of the group or if DNAT is used to send requests originating from this group to a server in the group.


This option only makes sense for ports on a bridge.
Check packets arriving on this port against the m[blue]shorewall6-blacklistm[][4](5) file.


Packets arriving from these hosts are checked for certain illegal combinations of TCP flags. Packets found to have such a combination of flags are handled according to the setting of TCP_FLAGS_DISPOSITION after having been logged according to the setting of TCP_FLAGS_LOG_LEVEL.


The zone is accessed via a kernel 2.6 ipsec SA. Note that if the zone named in the ZONE column is specified as an IPSEC zone in the m[blue]shorewall6-zonesm[][1](5) file then you do NOT need to specify the 'ipsec' option here.
