1 This module matches on the bridge port input and output devices enslaved
2 to a bridge device. This module is a part of the infrastructure that enables
3 a transparent bridging IP firewall and is only useful for kernel versions
6 .BR --physdev-in " [!] \fIname\fP"
7 Name of a bridge port via which a packet is received (only for
13 chains). If the interface name ends in a "+", then any
14 interface which begins with this name will match. If the packet didn't arrive
15 through a bridge device, this packet won't match this option, unless '!' is used.
17 .BR --physdev-out " [!] \fIname\fP"
18 Name of a bridge port via which a packet is going to be sent (for packets
24 chains). If the interface name ends in a "+", then any
25 interface which begins with this name will match. Note that in the
26 .BR nat " and " mangle
28 chains one cannot match on the bridge output port, however one can in the
30 chain. If the packet won't leave by a bridge device or it is yet unknown what
31 the output device will be, then the packet won't match this option, unless
34 .RB "[!] " --physdev-is-in
35 Matches if the packet has entered through a bridge interface.
37 .RB "[!] " --physdev-is-out
38 Matches if the packet will leave through a bridge interface.
40 .RB "[!] " --physdev-is-bridged
41 Matches if the packet is being bridged and therefore is not being routed.
42 This is only useful in the FORWARD and POSTROUTING chains.
