I recently installed CSF firewall. Immediately after this, my Munin has stopped showing me graphs for Connections through firewall and ipconntrack. I looked into log files and found this
2011/02/27-19:45:01 CONNECT TCP Peer: "192.168.156.237:57918" Local: "192.168.170.112:4949" 2011/02/27-19:45:16  Service 'fw_conntrack' timed out. 2011/02/27-19:45:29  Service 'fw_forwarded_local' timed out.
Any help as to whats happening? How can I debug this further
