IGMP Proxy Error Message for Logging Links to System Log Instead of Routing Log
If you try to apply a setting that won't apply in IGMP Proxy, it will state "There was a problem applying the changes. See the System Logs." with the "System" part of that message showing a blue link that goes to Status --> System Logs --> System. However, igmpproxy doesn't log to the System Log, but logs to the Routing Log instead, so this should be correctly tied.
