# Mark Packets in the forward chain
|
|
||||||
#
|
|
||||||
# When processing the tcrules file, Shorewall normally marks packets in the
|
|
||||||
# PREROUTING chain. To cause Shorewall to use the FORWARD chain instead, set
|
|
||||||
# this to "Yes". If not specified or if set to the empty value (e.g.,
|
|
||||||
# MARK_IN_FORWARD_CHAIN="") then MARK_IN_FORWARD_CHAIN=No is assumed.
|
|
||||||
#
|
|
||||||
# Marking packets in the FORWARD chain has the advantage that inbound
|
|
||||||
# packets destined for Masqueraded/SNATed local hosts have had their destination
|
|
||||||
# address rewritten so they can be marked based on their destination. When
|
|
||||||
# packets are marked in the PREROUTING chain, packets destined for
|
|
||||||
# Masqueraded/SNATed local hosts still have a destination address corresponding
|
|
||||||
# to the firewall's external interface.
|
|
||||||
#
|
|
||||||
# Note: Older kernels do not support marking packets in the FORWARD chain and
|
|
||||||
# setting this variable to Yes may cause startup problems.

#
|

# If this option is set to 'No' then Shorewall won't clear the current

# traffic control rules during [re]start. This setting is intended
|
|
||||||
# for use by people that prefer to configure traffic shaping when

|
||||||
# the network interfaces come up rather than when the firewall
|
|
||||||
# is started. If that is what you want to do, set TC_ENABLED=Yes and
|
|
||||||
# CLEAR_TC=No and do not supply an /etc/shorewall/tcstart file. That
|
|
||||||
# way, your traffic shaping rules can still use the 'fwmark'

<p><b>2/8/2003 - Shorewall 1.3.14</b><b> </b></p>
|
||||||
|
|
||||||
|
|
||||||
|
<p>New features include</p>
|
||||||
|
|
||||||
|
|
||||||
|
<ol>
|
||||||
|
<li>An OLD_PING_HANDLING option has been added
|
||||||
|
to shorewall.conf. When set to Yes, Shorewall ping handling is
|
||||||
|
as it has always been (see http://www.shorewall.net/ping.html).<br>
|
||||||
|
<br>
|
||||||
|
When OLD_PING_HANDLING=No, icmp echo (ping) is handled
|
||||||
|
via rules and policies just like any other connection request.
|
||||||
|
The FORWARDPING=Yes option in shorewall.conf and the 'noping' and
|
||||||
|
'filterping' options in /etc/shorewall/interfaces will all generate
|
||||||
|
an error.<br>
|
||||||
|
<br>
|
||||||
|
</li>
|
||||||
|
<li>It is now possible to direct Shorewall to create
|
||||||
|
a "label" such as "eth0:0" for IP addresses that it creates under
|
||||||
|
ADD_IP_ALIASES=Yes and ADD_SNAT_ALIASES=Yes. This is done by specifying
|
||||||
|
the label instead of just the interface name:<br>
|
||||||
|
<br>
|
||||||
|
a) In the INTERFACE column of /etc/shorewall/masq<br>
|
||||||
|
b) In the INTERFACE column of /etc/shorewall/nat<br>
|
||||||
|
</li>
|
||||||
|
<li>Support for OpenVPN Tunnels.<br>
|
||||||
|
<br>
|
||||||
|
</li>
|
||||||
|
<li>Support for VLAN devices with names of the
|
||||||
|
form $DEV.$VID (e.g., eth0.0)<br>
|
||||||
|
<br>
|
||||||
|
</li>
|
||||||
|
<li>In /etc/shorewall/tcrules, the MARK value may
|
||||||
|
be optionally followed by ":" and either 'F' or 'P' to designate that
|
||||||
|
the marking will occur in the FORWARD or PREROUTING chains respectively.
|
||||||
|
If this additional specification is omitted, the chain used to mark packets
|
||||||
|
will be determined by the setting of the MARK_IN_FORWARD_CHAIN option
|
||||||
|
in <a href="Documentation.htm#Conf">shorewall.conf</a>.<br>
|
||||||
|
<br>
|
||||||
|
</li>
|
||||||
|
<li>When an interface name is entered in the SUBNET
|
||||||
|
column of the /etc/shorewall/masq file, Shorewall previously masqueraded
|
||||||
|
traffic from only the first subnet defined on that interface. It
|
||||||
|
did not masquerade traffic from:<br>
|
||||||
|
<br>
|
||||||
|
a) The subnets associated with other addresses
|
||||||
|
on the interface.<br>
|
||||||
|
b) Subnets accessed through local routers.<br>
|
||||||
|
<br>
|
||||||
|
Beginning with Shorewall 1.3.14, if you enter an interface
|
||||||
|
name in the SUBNET column, shorewall will use the firewall's routing
|
||||||
|
table to construct the masquerading/SNAT rules.<br>
|
||||||
|
<br>
|
||||||
|
Example 1 -- This is how it works in 1.3.14.<br>

||||||

|

|
<br>
|
||||||
|
When upgrading to Shorewall 1.3.14, if you have multiple
|
||||||
|
local subnets connected to an interface that is specified in the
|
||||||
|
SUBNET column of an /etc/shorewall/masq entry, your /etc/shorewall/masq
|
||||||
|
file will need changing. In most cases, you will simply be able to remove
|
||||||
|
redundant entries. In some cases though, you might want to change from
|
||||||
|
using the interface name to listing specific subnetworks if the change
|
||||||
|
described above will cause masquerading to occur on subnetworks that you
|
||||||
|
don't wish to masquerade.<br>
|
||||||
|
<br>
|
||||||
|
Example 2 -- Suppose that your current config is as
|
||||||
|
follows:<br>
|
||||||
|
<br>
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
<pre> [root@gateway test]# cat /etc/shorewall/masq<br> #INTERFACE SUBNET ADDRESS<br> eth0 eth2 206.124.146.176<br> eth0 192.168.10.0/24 206.124.146.176<br> #LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE</pre>
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
<pre> [root@gateway test]# ip route show dev eth2<br> 192.168.1.0/24 scope link<br> 192.168.10.0/24 proto kernel scope link src 192.168.10.254<br> [root@gateway test]#</pre>
|
||||||
|
<br>
|
||||||
|
In this case, the second entry in /etc/shorewall/masq
|
||||||
|
is no longer required.<br>
|
||||||
|
<br>
|
||||||
|
Example 3 -- What if your current configuration is
|
||||||
|
like this?<br>
|
||||||
|
<br>
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
<pre> [root@gateway test]# cat /etc/shorewall/masq<br> #INTERFACE SUBNET ADDRESS<br> eth0 eth2 206.124.146.176<br> #LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE</pre>
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
<pre> [root@gateway test]# ip route show dev eth2<br> 192.168.1.0/24 scope link<br> 192.168.10.0/24 proto kernel scope link src 192.168.10.254<br> [root@gateway test]#</pre>
|
||||||
|
<br>
|
||||||
|
In this case, you would want to change the entry
|
||||||
|
in /etc/shorewall/masq to:<br>

||||||

||||||
|
|
||||||

|
||||||
|
<p>New features include</p>
|
||||||
|
|
||||||
|
|
||||||
|
<ol>
|
||||||
|
<li>An OLD_PING_HANDLING option has been added to shorewall.conf.
|
||||||
|
When set to Yes, Shorewall ping handling is as it has always been
|
||||||
|
(see http://www.shorewall.net/ping.html).<br>
|
||||||
|
<br>
|
||||||
|
When OLD_PING_HANDLING=No, icmp echo (ping) is handled
|
||||||
|
via rules and policies just like any other connection request. The
|
||||||
|
FORWARDPING=Yes option in shorewall.conf and the 'noping' and 'filterping'
|
||||||
|
options in /etc/shorewall/interfaces will all generate an error.<br>
|
||||||
|
<br>
|
||||||
|
</li>
|
||||||
|
<li>It is now possible to direct Shorewall to create
|
||||||
|
a "label" such as "eth0:0" for IP addresses that it creates under
|
||||||
|
ADD_IP_ALIASES=Yes and ADD_SNAT_ALIASES=Yes. This is done by specifying
|
||||||
|
the label instead of just the interface name:<br>
|
||||||
|
<br>
|
||||||
|
a) In the INTERFACE column of /etc/shorewall/masq<br>
|
||||||
|
b) In the INTERFACE column of /etc/shorewall/nat<br>
|
||||||
|
</li>
|
||||||
|
<li>Support for OpenVPN Tunnels.<br>
|
||||||
|
<br>
|
||||||
|
</li>
|
||||||
|
<li>Support for VLAN devices with names of the form
|
||||||
|
$DEV.$VID (e.g., eth0.0)<br>
|
||||||
|
<br>
|
||||||
|
</li>
|
||||||
|
<li>In /etc/shorewall/tcrules, the MARK value may be
|
||||||
|
optionally followed by ":" and either 'F' or 'P' to designate that the
|
||||||
|
marking will occur in the FORWARD or PREROUTING chains respectively.
|
||||||
|
If this additional specification is omitted, the chain used to mark packets
|
||||||
|
will be determined by the setting of the MARK_IN_FORWARD_CHAIN option
|
||||||
|
in <a href="Documentation.htm#Conf">shorewall.conf</a>.<br>
|
||||||
|
<br>
|
||||||
|
</li>
|
||||||
|
<li>When an interface name is entered in the SUBNET
|
||||||
|
column of the /etc/shorewall/masq file, Shorewall previously masqueraded
|
||||||
|
traffic from only the first subnet defined on that interface. It
|
||||||
|
did not masquerade traffic from:<br>
|
||||||
|
<br>
|
||||||
|
a) The subnets associated with other addresses on the
|
||||||
|
interface.<br>
|
||||||
|
b) Subnets accessed through local routers.<br>
|
||||||
|
<br>
|
||||||
|
Beginning with Shorewall 1.3.14, if you enter an interface
|
||||||
|
name in the SUBNET column, shorewall will use the firewall's routing
|
||||||
|
table to construct the masquerading/SNAT rules.<br>
|
||||||
|
<br>
|
||||||
|
Example 1 -- This is how it works in 1.3.14.<br>

<pre> [root@gateway test]# shorewall start<br> ...<br> Masqueraded Subnets and Hosts:<br> To 0.0.0.0/0 from 192.168.1.0/24 through eth0 using 206.124.146.176<br> To 0.0.0.0/0 from 192.168.10.0/24 through eth0 using 206.124.146.176<br> Processing /etc/shorewall/tos...</pre>
|
||||||
|
<br>
|
||||||
|
When upgrading to Shorewall 1.3.14, if you have multiple
|
||||||
|
local subnets connected to an interface that is specified in the
|
||||||
|
SUBNET column of an /etc/shorewall/masq entry, your /etc/shorewall/masq
|
||||||
|
file will need changing. In most cases, you will simply be able to remove
|
||||||
|
redundant entries. In some cases though, you might want to change from
|
||||||
|
using the interface name to listing specific subnetworks if the change described
|
||||||
|
above will cause masquerading to occur on subnetworks that you don't wish
|
||||||
|
to masquerade.<br>
|
||||||
|
<br>
|
||||||
|
Example 2 -- Suppose that your current config is as follows:<br>
|
||||||
|
<br>
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
<pre> [root@gateway test]# cat /etc/shorewall/masq<br> #INTERFACE SUBNET ADDRESS<br> eth0 eth2 206.124.146.176<br> eth0 192.168.10.0/24 206.124.146.176<br> #LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE</pre>
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
<pre> [root@gateway test]# ip route show dev eth2<br> 192.168.1.0/24 scope link<br> 192.168.10.0/24 proto kernel scope link src 192.168.10.254<br> [root@gateway test]#</pre>
|
||||||
|
<br>
|
||||||
|
In this case, the second entry in /etc/shorewall/masq
|
||||||
|
is no longer required.<br>
|
||||||
|
<br>
|
||||||
|
Example 3 -- What if your current configuration is like
|
||||||
|
this?<br>
|
||||||
|
<br>
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
<pre> [root@gateway test]# cat /etc/shorewall/masq<br> #INTERFACE SUBNET ADDRESS<br> eth0 eth2 206.124.146.176<br> #LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE</pre>
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
<pre> [root@gateway test]# ip route show dev eth2<br> 192.168.1.0/24 scope link<br> 192.168.10.0/24 proto kernel scope link src 192.168.10.254<br> [root@gateway test]#</pre>
|
||||||
|
<br>
|
||||||
|
In this case, you would want to change the entry in
|
||||||
|
/etc/shorewall/masq to:<br>
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
<pre> #INTERFACE SUBNET ADDRESS<br> eth0 192.168.1.0/24 206.124.146.176<br> #LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE</pre>
