Firewall Log Interface Filter Issue
The firewall log interface filter doesn't display LAN interface entries more than a “page” old unless a date is also added to the filter or the log entries to display per page setting is increased.
Put another way, only entries that are within the per page range are displayed. So if they are all beyond that scope, none are displayed.
Hope that makes sense.
Attached is a firewall widget patch I use that handles this with a tmp log enteries.
