This module matches on the bridge port input and output devices enslaved
|
|
to a bridge device. This module is a part of the infrastructure that enables
|
|
a transparent bridging IP firewall and is only useful for kernel versions
|
|
above version 2.5.44.
|
|
.TP
|
|
[\fB!\fP] \fB\-\-physdev\-in\fP \fIname\fP
|
|
Name of a bridge port via which a packet is received (only for
|
|
packets entering the
|
|
.BR INPUT ,
|
|
.B FORWARD
|
|
and
|
|
.B PREROUTING
|
|
chains). If the interface name ends in a "+", then any
|
|
interface which begins with this name will match. If the packet didn't arrive
|
|
through a bridge device, this packet won't match this option, unless '!' is used.
|
|
.TP
|
|
[\fB!\fP] \fB\-\-physdev\-out\fP \fIname\fP
|
|
Name of a bridge port via which a packet is going to be sent (for bridged packets
|
|
entering the
|
|
.BR FORWARD
|
|
and
|
|
.B POSTROUTING
|
|
chains). If the interface name ends in a "+", then any
|
|
interface which begins with this name will match.
|
|
.TP
|
|
[\fB!\fP] \fB\-\-physdev\-is\-in\fP
|
|
Matches if the packet has entered through a bridge interface.
|
|
.TP
|
|
[\fB!\fP] \fB\-\-physdev\-is\-out\fP
|
|
Matches if the packet will leave through a bridge interface.
|
|
.TP
|
|
[\fB!\fP] \fB\-\-physdev\-is\-bridged\fP
|
|
Matches if the packet is being bridged and therefore is not being routed.
|
|
This is only useful in the FORWARD and POSTROUTING chains.
