Subject: [PATCH] filtergw: add plugin allow to allow/block gateways (even
|
||||
smartgateway)
|
||||
|
||||
The plugin adds a possibility to filter out gateway HNAs. This can be
|
||||
very handy e.g. for faulty nodes. A gateway can be taken out directly on
|
||||
a central node and all traffic is then redirected. Also the underlying
|
||||
smart gateways are adapted. Currently the link multiplier is often used
|
||||
to control a faulty node, but it is not necessarily the best way to do
|
||||
so.
|
||||
|
||||
The plugin also allows to determine the smart gateway on the local node.
|
||||
This way you can easily select another gateway node to direct traffic,
|
||||
or block a specific one.
|
||||
|
||||
Here are some sample configurations:
|
||||
|
||||
Only allow Gateway HNA from '10.230.132.40':
|
||||
config LoadPlugin
|
||||
option library 'olsrd_filtergw'
|
||||
list originator '10.230.132.40'
|
||||
option allowlist '1'
|
||||
|
||||
Block Gateway HNA from '10.230.132.40':
|
||||
config LoadPlugin
|
||||
option library 'olsrd_filtergw'
|
||||
list originator '10.230.132.40'
|
||||
option allowlist '0'
|
||||
|
||||
The plugin is based on the work of sven-ola, pmelange and booo.
